In enzymology, an agaritine gamma-glutamyltransferase is an enzyme that catalyzes the chemical reaction agaritine + acceptor ⇌ {\displaystyle \rightleftharpoons } 4-hydroxymethylphenylhydrazine + gamma-L-glutamyl-acceptorThus, the two substrates of this enzyme are agaritine and acceptor, whereas its two products are 4-hydroxymethylphenylhydrazine and gamma-L-glutamyl-acceptor.
