Two glucose transport systems in Bacillus licheniformis.
Bacillus licheniformis NCIB 6346 showed active accumulation of glucose which was inhibited by agents which affect the transmembrane proton gradient. Phosphotransferase (PTS) activity, identified as phosphoenolpyruvate-dependent phosphorylation of glucose, was found in cell extracts but could not be demonstrated in cells permeabilized with toluene when assays were conducted at pH 6.6. The same w...
متن کاملThe isolation of structural components present in the cell wall of Bacillus licheniformis N.C.T.C. 6346.
1. Four of the known components of wall preparations of vegative cells of Bacillus licheniformis N.C.T.C. 6346 have been isolated free of each other after successive treatments of the walls with trichloroacetic acid and lysozyme: (a) a mucopeptide consisting of glucosamine, muramic acid, alphain-diaminopimelic acid, glutamic acid and alanine in the molar proportions 1.0:0.8:1.0:1.2:1.7; (b) an ...
متن کاملThe cell wall of Bacillus licheniformis N.C.T.C. 6346. Linkage between the teichuronic acid and mucopeptide components.
1. After extraction of teichoic acid from cell walls of Bacillus licheniformis with dilute alkali, the insoluble residue contains the teichuronic acid and mucopeptide components and a small amount of residual phosphorus. 2. A complex of teichuronic acid and a part of the mucopeptide was isolated from the soluble fraction obtained by lysozyme treatment of alkali extracted walls. 3. Small-molecul...
متن کاملEffect of temperature , pH , substrate ( Starch ) and glucose on stability of α - amylase from Bacillus licheniformis ATCC 6346
Thermostable α-amylases (1,4-α-D-glucan glucanohydrolase; E.C.3.2.1.1) from Bacillus species are of great industrial importance in the production of corn syrup or dextrose. The present study was aimed to determine the effect of temperature, pH, substrate and glucose on stability of α-amylase from Bacillus licheniformis ATCC 6346. To determine the effect of temperature and pH on the stability of...
متن کاملRegulation of alanine dehydrogenase in Bacillus (licheniformis).
Cell extracts of Bacillus licheniformis were found to contain nicotinamide adenine dinucleotide (NAD)-dependent l-alanine dehydrogenase (ADH) (l-alanine: NAD oxidoreductase, EC 1.4.1.1). High specific activities (3.5 to 6.0 IU/mg of protein) were found in extracts of cells throughout growth cycles only when l-alanine served as the primary source of carbon or carbon and nitrogen. Specific activi...
