RP IDENTIFICATION.
RG Ensembl;
RL Submitted (NOV-2023) to UniProtKB.
CC -!- FUNCTION: Regulatory subunit of S-adenosylmethionine synthetase 2, an
CC enzyme that catalyzes the formation of S-adenosylmethionine from
CC methionine and ATP. Regulates MAT2A catalytic activity by changing its
CC kinetic properties, increasing its affinity for L-methionine.
CC {ECO:0000256|RuleBase:RU364081}.
CC -!- PATHWAY: Amino-acid biosynthesis; S-adenosyl-L-methionine biosynthesis;
CC S-adenosyl-L-methionine from L-methionine: step 1/1.
CC {ECO:0000256|ARBA:ARBA00005224, ECO:0000256|RuleBase:RU364081}.
CC -!- SUBUNIT: Heterotrimer; composed of a catalytic MAT2A homodimer that
CC binds one regulatory MAT2B chain. Heterohexamer; composed of a central,
CC catalytic MAT2A homotetramer flanked on either side by a regulatory
CC MAT2B chain. NADP binding increases the affinity for MAT2A.
CC {ECO:0000256|RuleBase:RU364081}.
CC -!- SIMILARITY: Belongs to the dTDP-4-dehydrorhamnose reductase family.
CC MAT2B subfamily. {ECO:0000256|ARBA:ARBA00008656,
CC ECO:0000256|RuleBase:RU364081}.
