Autocatalytic cleavage of the GGT1 precursor polypeptide produces a heavy chain and a light chain that associate with each other to form the functional enzyme. Light chain-only GGTs, such as GGTLC3, contain a region corresponding to the GGT1 light chain, but they lack the membrane-anchoring heavy chain region (Heisterkamp et al., 2008 [PubMed 18357469]).[supplied by OMIM, Oct 2008]
