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 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...

متن کاملGermination of Bacillus megaterium spores after various extraction procedures.
The initiation of germination of Bacillus megaterium QM B1551 spores, grown in supplemented nutrient broth, has been studied. The initiation properties depend on buffer concentrations and the particular batch of spores. Initiation in l-alanine, KBr, calcium dipicolinate, or in buffer alone increases as a function of the spore age; whereas initiation in glucose, l-leucine, or l-proline remains r...
