Hydrazidase was an enzyme that remained unidentified for a half century. However, recently, it was purified, and its encoding gene was cloned. Microbacterium sp. strain HM58-2 grows with acylhydrazides as its sole carbon source; it produces hydrazidase and degrades acylhydrazides to acetate and hydrazides. The bacterial hydrazidase belongs to the amidase signature enzyme family and contains a Ser-cisSer-Lys catalytic motif. The condensation of hydrazine and carbonic acid produces various hydrazides, some of which are raw materials for synthesizing pharmaceuticals and other useful chemicals...
