What makes an enzyme promiscuous? pdf download

A different means to create promiscuous hybrid enzymes is to start from a substrate-binding pocket, which is the common denominator for the enviable efficiencies of natural enzymes, then apply and.

Request PDF | What makes an enzyme promiscuous? | Kinetic analyses of promiscuous enzymes reveal rate accelerations, (k(cat)/K(M))/k(2), of up to 10(18) for their secondary activities. Such large. Kinetic analyses of promiscuous enzymes reveal rate accelerations, (k cat /K M)/k 2, of up to 10 18 for their secondary bltadwin.ru large values suggest that binding and catalysis can be highly efficient for more than one reaction, challenging the notion that proficient catalysis requires specificity. Catalytic promiscuity and substrate ambiguity are keys to evolvability, which in turn is pivotal to the successful acquisition of novel biological functions. Action on multiple substrates (substrate ambiguity) can be harnessed for performance of functions in the cell that supersede catalysis of a single metabolite. These functions include proofreading, scavenging of nutrients, removal of.

Evidence suggests that novel enzyme functions evolved from low-level promiscuous activities in ancestral enzymes. Yet, the evolutionary dynamics and physiological mechanisms of how such side activities contribute to systems-level adaptations are.
