Résumé :

The coding sequence for the human pancreatic ribonuclease (HP-RNase) gene has been obtained from genomic DNA extracted from buccal epithelial cells. In order to direct the expression of the recombinant human pancreatic enzyme to the periplasmic space of E.coli, the bovine pancreatic RNase signal sequence has been fused 5' to the human gene. Initial attempts to express the recombinant enzyme were not successful, consequently site-directed mutagenesis tehniques were used to genetically engineer the HP-RNase gene to enable expression in E.coli. The resultant engineered enzyme shows similar kinetic characteristics to the homologous bovine enzyme.

Texte intégral

Résumé :

Chemoselective ligation between two peptides can be used to produce synthetic peptides and proteins that cannot easily be synthesised as single peptides by solid phase peptide synthesis. Chemoselective reaction between an aldehyde and hydrazine or hydroxylamine, masking the aldehyde as a 1, 2-amino alcohol, has been investigated as a method of sequential ligation that will allow synthesis of individual peptides in high yield and purity, enabling more than two peptides to be ligated. Protected amino acids were used as precursors for the synthesis of 1, 2-amino alcohol derivatives that could be used in solid phase peptide synthesis for the production of peptides bearing a C-terminal 1, 2-amino alcohol, as a masked aldehyde for use in ligation reactions. Limitations of this method led to alternative investigations, using peptides bearing an N-terminal serine as a masked aldehyde, and a C-terminal hydrazide. Bovine pancreatic ribonuclease A was chosen as an example protein for sequential ligation and using this method, peptides were synthesised in high yield and purity for use in ligation reactions. Trial ligation reactions with short test peptides were performed successfully, however problems were experienced during ligations using peptide fragments of ribunuclease due to involvement of the cysteine side chains. Methods to overcome these unwanted reactions resulted in insoluble peptide fragments. Computer modelling using molecular dynamics simulations has been used to investigate the effect of replacing native peptide bonds in ribonuclease on the structure of the protein. The method of molecular dynamics simulation was validated through comparison of the structure of a mutant of ribonuclease from experimental NMR data to the structure produced after a molecular dynamics simulation. Results of the modelling simulations suggest that replacement of native peptide bonds with the chemoselective bond formed through reaction of an aldehyde and hydrazine will have only minor implications for the structure of ribonuclease, and therefore should only have a small impact on enzyme activity .

Résumé :

Understanding enzyme catalysis is one of the major goals in biology. Ribonuclease A (RNase A) is a key system to understanding protein structure and function provides an attractive system to investigate the catalytic role of active site interactions. Crystal structures show a lysine residue (Lys41) situated in the RNase A active site, and mutagenesis studies suggest this residue is important for catalysis. To evaluate the catalytic importance of the Lys41-phosphate interaction, double mutant cycle analysis was used. Individual mutation of lysine to arginine (K41R) and substitution of a phosphate oxygen with sulfur led to ∼350 and ∼100-fold decrease in k_cat/K_M, respectively. However, in the K41R background, substitution of the same oxygen with sulfur decreased activity by a similar amount (within 2-fold) as it did with the wild-type enzyme. This result provides evidence that functional interaction between Lys41 and the phosphate backbone of RNA substrates may not be solely limited between the two groups.

Résumé :

Hypercholesterolemia and hypertension are major growing concerns that are managed by drugs that inhibit various metabolic enzymes. Milk hydrolysates have been reported to contain various bioactive peptides (BAP) that can inhibit various metabolic enzymes for enhancing human health. As such camel whey proteins were subjected to peptic hydrolysis using a full factorial model (33) with hydrolysis time, temperature, and enzyme concentration as factors. The resulting hydrolysates were analyzed for anti-hypercholesterolemic and hypertensive properties by studying the in vitro inhibition of various enzymatic markers. The hydrolysates with lowest IC50 values were further subjected to LC-MS-QTOF that revealed presence of 185 peptides. Selected peptides that had Peptide Ranker Score greater than 0.8 were further studied for prediction of possible interactions with enzyme markers: pancreatic lipase (PL) cholesterol esterase (CE) and angiotensin converting enzyme (ACE) using in silico analysis. The data generated suggested that most of the peptides could bind active site of PL while as only three peptides could bind active site of CE. Based on higher number of reactive residues in the bioactive peptides (BAP) and greater number of substrate binding sites, FCCLGPVPP was identified as potential CE inhibitory peptide while PAGNFLPPVAAAPVM, MLPLMLPFTMGY, and LRFPL were identified as PL inhibitors. While peptides PAGNFLP, FCCLGPVPP, PAGNFLMNGLMHR, PAVACCLPPLPCHM were identified as potential ACE inhibitors. Molecular docking of selected peptides showed hydrophilic and hydrophobic interactions between peptides and target enzymes. Moreover, due to the importance of renin in managing hypertension, peptides from hydrolysates with high ACE inhibiting potential were predicted for potential to interact with renin using in silico analysis. Molecular docking was subsequently employed to identify how the identified peptides, PVAAAPVM and LRPFL, could interact with renin and potentially inhibit it. Thus, non-bovine (camel) whey hydrolysates might be used as functional ingredients for production of functional foods with antihypertensive and anticholesterolemic properties.

Résumé :

U-PA is released from many cells as a single polypeptide chain (scu-PA) that is converted into its active two-chain form (tcu-PA) by limited proteolysis with plasmin. There is general agreement that scu-PA has an extremely low amidolytic activity, but different oppinions exist, as to whether scu-PA itself can activate plasminogen. We have reinvestigated the plasminogen activating activity of our scu-PA preparations by means of a direct [125]I-plasminogen conversion assay and two amidolytic assays for plasmin and u-PA activity. In the [125]I-plasminogen conversion assay in the presence of bovine pancreatic trypsin inhibitor (BPTI) the subsequent plasmin catalyzed conversion of scu-PA is blocked while the plasminogen activation is unaffected. In this assay with 3oo nM Glu-plasminogen and 15 pM BPTI, 4o nM scu-PA caused a low but significant plasminogen conversion, which could be fully inhibited by pretreatment of scu-PA with diisopropylfluorophos-phate (DFP). DFP-treated scu-PA was convertible to fully active tcu-PA. Rates of plasminogen activation in this type of assay for scu-PA activity was at least 4oo fold slower than that measured for tcu-PA. A coupled amidolytic assay with Lys-plasminogen, scuPA or tcu-PA, BPTI, and the high affinity plasmin substrate H-D-Val-Phe-LyspNA (S2390) was performed under conditions that ensures a low steady state concentration of free plasmin. In this assay the initial rate of Lys-plasminogen activation by DFP-treated scu-PA was at least 25o fold slower than that measured for tcu-PA. Finally, u-PA activity was measured in an assay with the chromogenic substrate <Glu-Gly-ArgpNA (S2444) (o.8mM) in the presence of highly purified Glu-plasminogen (3oonM) and DFP-treated scu-PA (2nM) in the absence of BPTI. Within the initial 15 min of incubation no detectable hydrolysis of S2444 occurred. Addition of tcu-PA (2pM) or plasmin (o.lnM) to the scu-PA/Glu-plasminogen mixture caused a significant reduction of the lag period before onset of the cascade reaction leading to scu-PA conversion and subsequent hydrolysis of S2444. We conclude that the low rates of plasminogen activation measured in these assays by scu-PA might be accounted for by the presence of trace amounts of tcu-PA in the scu-PA preparations, and that scu-PA meets the requirements for a genuine proenzyme
