Penicillin G Acylase (PGA)

Target
PGA
Molecular classification
Enzyme, Hydrolase
01

Overview

Penicillin G acylase (PGA) is an enzyme crucial in the industrial production of semi-synthetic β-lactam antibiotics. It catalyzes the hydrolysis of penicillin G into 6-aminopenicillanic acid (6-APA), a key building block for many common antibiotics like ampicillin and amoxicillin. It also hydrolyzes cephalosporin G. PGA is favored over chemical processes due to its efficiency and environmental benefits.
