Phospholipid metabolism and membrane synthesis during sporulation in Bacillus megaterium.
In view of previously published reports of localized membrane growth in exponentially growing Bacillus megaterium and in sporulating Bacillus cereus, an attempt was made to describe phospholipid metabolism and the topology of membrane synthesis during sporulation in B. megaterium. The cells were pulsed with radioactive glycerol or acetate at the time of septum formation, and the specific activi...
متن کاملMucopeptide metabolism during growth and sporulation in Bacillus megaterium.
A mutant of Bacillus megaterium lacking the aspartate P-semialdehyde-pyruvate-condensing enzyme and mesodiaminopimelic acid decarboxylase has been used in a study of mucopeptide metabolism during growth and sporulation. The absolute requirement for both diaminopimelic acid and lysine in this mutant guarantees that exogenous labeled diaminopimelic acid is incorporated specifically into mucopepti...
متن کاملSynchronous growth and sporulation of Bacillus megaterium.
Filtration of late log-phase cultures of Bacillus megaterium ATCC 19213 grown on defined sucrose salts medium (SS) or SS plus glutamate medium (SSG) through nine layers of Whatman no. 40 filter paper in a fritted-glass disc Büchner funnel resulted in filtrates containing cells which showed synchronous growth and proceeded to sporulation. SS cells completed one synchronous division after filtrat...
متن کاملProtein Metabolism during Germination of Bacillus megaterium Spores
Two distinct proteolytic systems have been detected during germination of Bacillus megaterium spores: one degrading a unique class of dormant spore proteins and the other degrading primarily protein synthesized during germination. Proteolysis of dormant spore protein began by the 3rd min of germination and by 25 min had degraded 15 to 20% of the pre-existing protein to free amino acids. This re...
