SMT — Brassica juncea

Summary

BJUA04G00140S (symbol SMT, preferred name BjHMT2) encodes a homocysteine S-methyltransferase with selenocysteine methyltransferase activity, S-adenosylmethionine-homocysteine S-methyltransferase activity, and S-methylmethionine-homocysteine S-methyltransferase activity, and binds zinc and other metals. The protein localises to the cytosol and cytoplasm. This gene is associated with the S-methylmethionine cycle, methionine biosynthesis, amino acid metabolism, and response to selenium ion. It has been linked to chlorophyll content and plant height, and to seed methionine content. Related genes in other species are linked to methionine synthesis and increased seed methionine content.
