S161A MUTANT OF BACILLUS SUBTILIS OXALATE DECARBOXYLASE OXDC

Overview

Oxalate decarboxylase (EC 4.1.1.2) catalyses the conversion of oxalate to, carbon dioxide and formate. It requires manganese and, uniquely, dioxygen, for catalysis. It forms a homohexamer and each subunit contains two, similar, but distinct, manganese sites termed sites 1 and 2. There is, kinetic evidence that only site 1 is catalytically active and that site 2, is purely structural. However, the kinetics of enzymes with mutations in, site 2 are often ambiguous and all mutant kinetics have been interpreted, without structural information. Nine new site-directed mutants have been, generated and four mutant crystal structures have now been solved. Most, mutants targeted either the flexibility (T165P), favoured conformation, (S161A, S164A, D297A or H299A) or presence (Delta162-3 or ... [(full description)]
