Nucleotide sequence of threonine tRNA from Bacillus subtilis.
A threonine tRNA was purified from Bacillus subtilis W168 by a combined use of column chromatographic systems. The nucleotide sequence was determined to be pG-C-C-G-G-U-G-U-A-G-C-U-C-A-A-U-D-G-G-D(U)-A-G-A-G-C-A-A-C-U-G-A-C-U-mo5U-G-U-t6A-A-psi-C-A-G-U-A-G-m7G-U-U-G-G-G-G-G-T-psi-C-A-A-G-U-C-C-U-C-U-U-G-C-C-G-G-C-A-C-C-AOH, where about 40 % of D20 remained unmodified as U20. It consists of 76 n...
متن کاملMutants of Bacillus subtilis
Enzyme activities of glycolysis and glyconeogenesis are present in spores of Bacillus subtilis, the rate-limiting step of glucose (GLC) metabolism being its phosphorylation. GLC allows initiation of germination in the presence of fructose (FRU) and asparagine (ASN), not because it is used via the EmbdenMeyerhof path, but because it is oxidized in the nonphosphorylated form via the spore-specifi...
متن کاملThe serine/threonine/tyrosine phosphoproteome of the model bacterium Bacillus subtilis.
Protein phosphorylation on serine, threonine, and tyrosine (Ser/Thr/Tyr) is well established as a key regulatory posttranslational modification in eukaryotes, but little is known about its extent and function in prokaryotes. Although protein kinases and phosphatases have been predicted and identified in a variety of bacterial species, classical biochemical approaches have so far revealed only a...
متن کاملThreonine synthetase of Bacillus subtilis. The nature of an associated dehydratase activity.
The gene encoding threonine synthetase has been located by genetic transformation in Bacillus subtilis. Its position is adjacent and central to the genes encoding homoserine dehydrogenase and homoserine kinase. Its mutational sites are closely linked to, and interspersed among, several mutational sites affecting a minor but phenotypically significant threonine dehydratase (distinct from the maj...
متن کاملImpact of Serine/Threonine Protein Kinases on the Regulation of Sporulation in Bacillus subtilis
Bacteria possess many kinases that catalyze phosphorylation of proteins on diverse amino acids including arginine, cysteine, histidine, aspartate, serine, threonine, and tyrosine. These protein kinases regulate different physiological processes in response to environmental modifications. For example, in response to nutritional stresses, the Gram-positive bacterium Bacillus subtilis can differen...
