Biochemistry of L-proline-triggered germination of Bacillus megaterium spores.
The mechanism by which L-proline triggers germination in Bacillus megaterium QM B1551 spores was investigated. First, brief exposure of spores to L-proline, followed by dilution, was sufficient to trigger germination. Once germination was triggered, the spores continued initiation of germination and did not require high concentrations of L-proline. Triggering of germination was pH and temperatu...
متن کاملGlucose catabolism during germination of Bacillus megaterium spores.
When heat-activated spores of Bacillus megaterium germinated in glucose-containing medium, 10 to 30% of the glucose was found to be oxidized to gluconate.
متن کاملActivation energy for glucose-induced germination of Bacillus megaterium spores.
The maximum germination rate of Bacillus megaterium QM B1551 spores in glucose increased, and the lag before its attainment decreased, with increasing germination temperature. The activation energy for germination (mu = approximately 20 kcal/mole), based on rate or on lag, was consistent with an enzymatic mechanism.
متن کاملCrystal Structure of Germination Protease from Spores of Bacillus Megaterium
No. ponn1490 Beamline(s): X12C Cells of Bacillus and Clostridium species produce spores when one or more nutrients are limiting for growth of these organisms. The spores DNA is saturated with a group of small, acid-soluble proteins (SASP) of the α/βtype. In spore germination SASP are degraded to amino acids and this degradation is initiated by a sequence specific protease called the germination...
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...
