>TIGR01767 MTRK 5-methylthioribose kinase; InterPro: IPR009212 Members of this family are 5-methylthioribose kinases (2.7.1.100 from EC) that catalyse phosphorylation of 5-methylthioribose (MTR), a step in the recycling of methionine from 5'-methylthioadenosine, a co-product of polyamine biosynthesis. The preceding step of methylthioadenosine (MTA) hydrolysis to MTR is catalysed by 5'-methylthioadenosine/S-adenosylhomocysteine (MTA/AdoHcy) nucleosidase (PIRSF006618 from PIRSF). Bacillus subtilis MtnK (formerly YkrT) and Klebsiella pneumoniae MtrK have been experimentally characterised. Klebsiella pneumoniae MtrK expression is regulated by methionine . As this enzyme is absent in mammals, it has been considered a target for rational drug design.; GO: 0046522 S-methyl-5-thioribose kinase activity, 0009086 methionine biosynthetic process.
