Enzymes for Research, Diagnostic and Industrial Use

Phosphotransacetylase from Bacillus subtilis, Recombinant

Cat No.
NATE-1120
Description
Phosphotransacetylase converts CoA to acetyl CoA. This enzyme belongs to the family of transferases, specifically those acyltransferases transferring groups other than aminoacyl groups. This enzyme participates in 3 metabolic pathways:taurine and hypotaurine metabolism, pyruvate metabolism, and propanoate metabolism.
