DESCRIPTION

Also known as MTN1_ARATH, MTN1, MTAN, MTAN1. Enzyme of the methionine cycle that catalyzes the irreversible cleavage of the glycosidic bond in 5'-methylthioadenosine (MTA) to adenine and 5'-methylthioribose (PubMed:19249293, PubMed:18342331). Contributes to the maintenance of AdoMet homeostasis and is required to sustain high rates of ethylene synthesis. Inactive towards S-adenosylhomocysteine (SAH/AdoHcy) (PubMed:18342331, PubMed:19249293). Homodimer (PubMed:19249293, PubMed:16909418). Interacts with CBL3 in a calcium-dependent manner.
