Native and recombinant Pg-AMP1 show different antibacterial activity spectrum but similar folding behavior
Glycine-rich proteins (GRPs) derived from plants compose a family of proteins and peptides that share a glycine repeat domain and they can perform diverse functions. Two structural conformations have been proposed for GRPs: glycine loops arranged as a Velcro and an anti-parallel β-sheet with several β-strands. The antimicrobial peptide Pg-AMP1 is the only plant GRP with antibacterial activity r...
متن کاملProteins with Highly Similar Native Folds Can Show Vastly Dissimilar Folding Behavior When Desolvated**
Proteins can be exposed to vastly different environments such as the cytosol or membranes, but the delicate balance between external factors and intrinsic determinants of protein structure, stability, and folding is only poorly understood. Here we used electron capture dissociation to study horse and tuna heart Cytochromes c in the complete absence of solvent. The significantly different stabil...
متن کاملAntimicrobial activity of recombinant Pg-AMP1, a glycine-rich peptide from guava seeds
Antimicrobial peptides (AMPs) are compounds that act in a wide range of physiological defensive mechanisms developed to counteract bacteria, fungi, parasites and viruses. These molecules have become increasingly important as a consequence of remarkable microorganism resistance to common antibiotics. This report shows Escherichia coli expressing the recombinant antimicrobial peptide Pg-AMP1 prev...
متن کاملBiological Activity Analysis of Native and Recombinant Streptokinase Using Clot Lysis and Chromogenic Substrate Assay
Determination of streptokinase activity is usually accomplished through two assay methods: a) Clot lysis, b) Chromogenic substrate assay. In this study the biological activity of two streptokinase products, namely Streptase®, which is a native product and Heberkinasa®, which is a recombinant product, was determined against the third international reference standard using the two forementioned a...
متن کاملEfficacy of antidepressants: similar but different.
Fountoulakis & Moller (2010) have re-analysed the Kirsch et al. (2008) meta-analysis of newer antidepressants and reached quite different conclusions to the original study. In particular they highlight that both venlafaxine and paroxetine exceed the NICE criteria for ‘clinical significance’ of 3 points on the Hamilton Rating Scale for Depression (HAMD) and that the Kirsch et al. analysis undere...
