Characterization of a mannose utilization system in Bacillus subtilis.
The mannose operon of Bacillus subtilis consists of three genes, manP, manA, and yjdF, which are responsible for the transport and utilization of mannose. Upstream and in the same orientation as the mannose operon a regulatory gene, manR, codes for a transcription activator of the mannose operon, as shown in this study. Both mannose operon transcription and manR transcription are inducible by m...
متن کاملGlucomannan utilization operon of Bacillus subtilis.
This study characterizes the glucomannan utilization operon (gmuBACDREFG, formerly ydhMNOPQRST) of Bacillus subtilis. Transcription of the operon is induced by konjac glucomannan and requires the last mannanase gene (gmuG). Cellobiose and mannobiose, possible degradation products of glucomannan by GmuG, are strong inducers of transcription. It is shown that an internal regulator gene (gmuR) enc...
متن کاملCharacterization of Bacillus subtilis hemN.
A recently cloned Bacillus subtilis open reading frame (hemN) upstream of the dnaK operon was identified as encoding a protein involved in oxygen-independent coproporphyrinogen III decarboxylation. B. subtilis hemN functionally complemented two Salmonella typhimurium hemF hemN double mutants under aerobic and anaerobic conditions. A B. subtilis hemN mutant accumulated coproporphyrinogen III onl...
متن کامل5-bromouracil utilization by Bacillus subtilis.
The replacement of thymine (T) in deoxyribonucleic acid (DNA) by 5-bromouracil (BU) (F. Weygand, A. Wacker, and H. Dellweg, Z. Naturforsch. 7b:19, 1952) is an aid in density separation of types of DNA, and in studies on radiobiology and mutagenesis. The usefulness of BU is, however, limited by its toxic effects. Extensive substitution in DNA of T by BU is lethal for most Escherichia coli and Ba...
متن کاملMaltose and maltodextrin utilization by Bacillus subtilis.
Bacillus subtilis can utilize maltose and maltodextrins that are derived from polysaccharides, like starch or glycogen. In this work, we show that maltose is taken up by a member of the phosphoenolpyruvate-dependent phosphotransferase system and maltodextrins are taken up by a maltodextrin-specific ABC transporter. Uptake of maltose by the phosphoenolpyruvate-dependent phosphotransferase system...
