| Comments |
The enzyme, which occurs only in animals and plants, can be either endo- and/or exopeptidase. It acts on tetrahydropteroyl polyglutamates and their modified forms, as well as the polyglutamates of the folate breakdown product?N-(4-aminobenzoyl)-L-glutamate (pABA-Glu). The initial cleavage may release either monoglutamate or poly-¦Ã-glutamate of two or more residues, depending on the specific enzyme. For example, GGH1 from the plant?Arabidopsis thaliana?cleaves pentaglutamates, mainly to di- and triglutamates, whereas GGH2 from the same organism yields mainly monoglutamates. The enzyme is lysosomal (and secreted) in animals and vacuolar in plants. Belongs to peptidase family?C26. Formerly EC?3.4.12.10?and EC?3.4.22.12. |
