RL Submitted (MAY-2013) to the EMBL/GenBank/DDBJ databases.
CC -!- FUNCTION: Catalyzes the interconversion of methylthioribose-1-phosphate
CC (MTR-1-P) into methylthioribulose-1-phosphate (MTRu-1-P).
CC {ECO:0000256|HAMAP-Rule:MF_01678}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=S-methyl-5-thio-alpha-D-ribose 1-phosphate = S-methyl-5-thio-
CC D-ribulose 1-phosphate; Xref=Rhea:RHEA:19989, ChEBI:CHEBI:58533,
CC ChEBI:CHEBI:58548; EC=5.3.1.23; Evidence={ECO:0000256|HAMAP-
CC Rule:MF_01678};
CC -!- PATHWAY: Amino-acid biosynthesis; L-methionine biosynthesis via salvage
CC pathway; L-methionine from S-methyl-5-thio-alpha-D-ribose 1-phosphate:
CC step 1/6. {ECO:0000256|HAMAP-Rule:MF_01678}.
CC -!- SIMILARITY: Belongs to the EIF-2B alpha/beta/delta subunits family.
CC MtnA subfamily. {ECO:0000256|HAMAP-Rule:MF_01678}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
CC {ECO:0000313|EMBL:EQA62808.1}.
