Kinetic Studies of the Native and Mutated Intracellular ß-Glucosidases from Cellulomonas biazotea
Abstract:The mutation, conferring streptomycin and deoxyglucose resistance on cells, had profound effect on the kinetic and thermodynamic parameters inferring thermostabilization of ß-glucosidase from mutant 51 SMr of Cellulomonas biazotea. Free energy of activation for substrate binding, enthalpy and entropy of activation for irreversible denaturation of mutant-derived enzyme were decreased compared with enzyme from wild organism suggesting that the mutation partly stabilized the enzyme and that mutation made it more reactive.

More about this publication?
- Protein & Peptide Letters publishes short papers in all important aspects of protein and peptide research, including structural studies, recombinant expression, function, synthesis, enzymology, immunology, molecular modeling, drug design etc. Manuscripts must have a significant element of novelty, timeliness and urgency that merit rapid publication. Reports of crystallisation, and preliminary structure determinations of biologically important proteins are acceptable. Purely theoretical papers are also acceptable provided they provide new insight into the principles of protein/peptide structure and function.
