OC Bacteria; Firmicutes; Bacillales; Bacillaceae; Bacillus; OC Bacillus cereus group. OX NCBI_TaxID=568206; RN [1] RP NUCLEOTIDE SEQUENCE [LARGE SCALE GENOMIC DNA]. RA Dodson R.J., Munk A.C., Brettin T., Bruce D., Detter C., Tapia R., RA Han C., Sutton G., Sims D.; RT "Genome sequence of Bacillus anthracis str. CDC 684."; RL Submitted (OCT-2008) to the EMBL/GenBank/DDBJ databases. CC -!- FUNCTION: Catalyzes the dehydration of methylthioribulose-1- CC phosphate (MTRu-1-P) into 2,3-diketo-5-methylthiopentyl-1- CC phosphate (DK-MTP-1-P) (By similarity). CC -!- CATALYTIC ACTIVITY: S-methyl-5-thio-D-ribulose 1-phosphate = 5- CC (methylthio)-2,3-dioxopentyl phosphate + H(2)O. CC -!- COFACTOR: Binds 1 zinc ion per subunit (By similarity). CC -!- PATHWAY: Amino-acid biosynthesis; L-methionine biosynthesis via CC salvage pathway; L-methionine from S-methyl-5-thio-alpha-D-ribose CC 1-phosphate: step 2/6. CC -!- SUBUNIT: Homotetramer (By similarity). CC -!- SIMILARITY: Belongs to the aldolase class II family. MtnB CC subfamily.
