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}.
