CC -!- FUNCTION: Catalyzes the phosphorylation of methylthioribose into
CC methylthioribose-1-phosphate. {ECO:0000255|HAMAP-Rule:MF_01683}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=5-(methylsulfanyl)-D-ribose + ATP = ADP + H(+) + S-methyl-5-
CC thio-alpha-D-ribose 1-phosphate; Xref=Rhea:RHEA:22312,
CC ChEBI:CHEBI:15378, ChEBI:CHEBI:30616, ChEBI:CHEBI:58533,
CC ChEBI:CHEBI:78440, ChEBI:CHEBI:456216; EC=2.7.1.100;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_01683};
CC -!- PATHWAY: Amino-acid biosynthesis; L-methionine biosynthesis via salvage
CC pathway; S-methyl-5-thio-alpha-D-ribose 1-phosphate from S-methyl-5'-
CC thioadenosine (hydrolase route): step 2/2. {ECO:0000255|HAMAP-
CC Rule:MF_01683}.
CC -!- SUBUNIT: Homodimer. {ECO:0000255|HAMAP-Rule:MF_01683}.
CC -!- SIMILARITY: Belongs to the methylthioribose kinase family.
CC {ECO:0000255|HAMAP-Rule:MF_01683}.
