Pathwayi: L-methionine biosynthesis via de novo pathway

This protein is involved in step 1 of the subpathway that synthesizes L-methionine from L-homocysteine (BhmT route).UniRule annotation
Proteins known to be involved in this subpathway in this organism are:
  1. cDNA, FLJ96222, highly similar to Homo sapiens betaine-homocysteine methyltransferase (BHMT), mRNA, Betaine-homocysteine methyltransferase, isoform CRA_a (HEL-S-61p), cDNA FLJ54604, highly similar to Betaine--homocysteine S-methyltransferase (EC 2.1.1.5), S-methylmethionine--homocysteine S-methyltransferase BHMT2 (BHMT2), Betaine--homocysteine S-methyltransferase 1 (BHMT), cDNA, FLJ96586, highly similar to Homo sapiens betaine-homocysteine methyltransferase 2 (BHMT2), mRNA, Betaine-homocysteine methyltransferase 2, isoform CRA_c (BHMT2), Betaine--homocysteine S-methyltransferase 1 (BHMT)
This subpathway is part of the pathway L-methionine biosynthesis via de novo pathway, which is itself part of Amino-acid biosynthesis.
View all proteins of this organism that are known to be involved in the subpathway that synthesizes L-methionine from L-homocysteine (BhmT route), the pathway L-methionine biosynthesis via de novo pathway and in Amino-acid biosynthesis.
