Sysname
amidinoproclavaminate amidinohydrolase
Reaction(IUBMB)
amidinoproclavaminate + H2O = proclavaminate + urea [RN:R05357]
Reaction(KEGG)
R05357
Substrate
amidinoproclavaminate [CPD:C06657];
H2O [CPD:C00001]
Product
proclavaminate [CPD:C06658];
urea [CPD:C00086]
Comment
Forms part of the pathway for the biosythesis of the beta-lactamase inhibitor clavulanate in Streptomyces clavuligerus. It carries out an intermediary reaction between the first reaction of EC 1.14.11.21, clavaminate synthase, and the second and third reactions of that enzyme. Requires Mn2+.
