acceptor Acceptor may refer to: * Acceptor (accounting), the addressee of a bill of exchange * In the Indian Contract Act of 1872, the acceptor is the person to whom a proposal is made, and who has communicated his or her acceptance of the said proposal ...

, whereas its two products are 4-hydroxymethylphenylhydrazine and gamma-L-glutamyl-acceptor. This enzyme belongs to the family of transferases, specifically the

aminoacyltransferase Aminoacyltransferases () are acyltransferase enzymes which act upon an amino group. For instance, aminoacyl tRNA synthetases attach an aminoacid through esterification to the corresponding tRNA. The activation of amino acids it aminoacyl-tRNA synt ...

s. The systematic name of this enzyme class is (gamma-L-glutamyl)-N1-(4-hydroxymethylphenyl)hydrazine:acceptor gamma-glutamyltransferase. Other names in common use include (gamma-L-glutamyl)-N1-(4-hydroxymethylphenyl)hydrazine:(acceptor), gamma-glutamyltransferase, (gamma-L-glutamyl)-1-N-(4-hydroxymethylphenyl)hydrazine:(acceptor), gamma-glutamyltransferase, (gamma-L-glutamyl)-1-N-(4-hydroxymethylphenyl)hydrazine:acceptor, and gamma-glutamyltransferase.
