Heptaprenylpyrophosphate synthetase from Bacillus subtilis.
Heptaprenyl pyrophosphate synthetase was detected in partially purified extracts of Bacillus subtilis. The enzyme catalyzed the synthesis of all-trans C35 prenyl pyrophosphate from isopentenyl pyrophosphate and farnesyl or geranylgeranyl pyrophosphate, but it did not catalyze a reaction between isopentenyl pyrophosphate and either dimethylallyl or geranyl pyrophosphate. The enzyme reaction proc...
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 کاملTranslocation of mycobacillin synthetase in Bacillus subtilis.
The extracellular release of mycobacillin from Bacillus subtilis first occurred in the medium at the onset of stationary phase and continued at a high rate even after 6 days. Mycobacillin synthetase activity appeared earlier than late-exponential phase in the cytosol of producer cells and was not sedimentable even at 105 000 g. The activity then quickly reached the maximum late in the stationar...
متن کاملNucleotide 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 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...
