Stage V sporulation germinant protein; Evidence 1a: Function experimentally demonstrated in the studied strain; Product type cp: cell process.

Stage V sporulation protein AA; Evidence 1a: Function experimentally demonstrated in the studied strain; Product type cp: cell process.

Spore endopeptidase; Initiates the degradation of small, acid-soluble proteins during spore germination.

Spore germinant protein; Evidence 1a: Function experimentally demonstrated in the studied strain; Product type cp: cell process.

Spore cortex-lytic enzyme; Could be a lytic transglycosylase. Required for spore cortex hydrolysis during germination. Interacts strongly but noncovalently with spore components.

RNA polymerase sporulation-specific sigma factor (sigma-F); Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released. This sigma factor is responsible for the expression of sporulation specific genes. Interaction with SpoIIAB inhibits sigma-F activity throughout the cell before the formation of the asymmetric septum; after septation the interaction is confined to the mother cell, and sigma F activity is released in the prespore. Responsible for expression of csfB (the anti-sigma-G factor Gin).

Component of the GerA germination receptor; Forms a complex at the inner spore membrane which acts as a receptor for L-alanine, thus is involved in the stimulation of germination in response to alanine. Can stimulate germination in the absence of GerD and GerK gene products (fructose and glucose receptors, respectively), but the response is improved in their presence.
