Maltose 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...
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 کاملProline utilization by Bacillus subtilis: uptake and catabolism.
L-Proline can be used by Bacillus subtilis as a sole source of carbon or nitrogen. We traced L-proline utilization genetically to the putBCP (ycgMNO) locus. The putBCP gene cluster encodes a high-affinity proline transporter (PutP) and two enzymes, the proline dehydrogenase PutB and the Δ(1)-pyrroline-5-carboxylate dehydrogenase PutC, which jointly catabolize L-proline to L-glutamate. Northern ...
متن کاملRoles of maltodextrin and glycogen phosphorylases in maltose utilization and glycogen metabolism in Corynebacterium glutamicum.
Corynebacterium glutamicum transiently accumulates large amounts of glycogen, when cultivated on glucose and other sugars as a source of carbon and energy. Apart from the debranching enzyme GlgX, which is required for the formation of maltodextrins from glycogen, alpha-glucan phosphorylases were assumed to be involved in glycogen degradation, forming alpha-glucose 1-phosphate from glycogen and ...
متن کاملMaltose and Maltodextrin Utilization by Listeria monocytogenes Depend on an Inducible ABC Transporter which Is Repressed by Glucose
BACKGROUND In the environment as well as in the vertebrate intestine, Listeriae have access to complex carbohydrates like maltodextrins. Bacterial exploitation of such compounds requires specific uptake and utilization systems. METHODOLOGY/PRINCIPAL FINDINGS We could show that Listeria monocytogenes and other Listeria species contain genes/gene products with high homology to the maltodextrin ...
