A cholera enterotoxin subunit A isoform 1 that has been processed by proteolytic cleavage to yield the catalytic subunit of subunit A. The cholera holotoxin consists of a pentameric ring of B subunits whose central pore is occupied by the A subunit. The A subunit contains two chains, A1 and A2, linked by a disulfide bridge.
