Protein Family Models

The GerAC protein of the Bacillus subtilis spore is required for the germination response to L-alanine. Members of this family are thought to be located in the inner spore membrane. Although the function of this family is unclear, they are likely to encode the components of the germination apparatus that respond directly to this germinant, mediating the spore's response [1].

Members of this protein family are restricted to endospore-forming members of the Firmicutes lineage of bacteria, including the genera Bacillus, Clostridium, Thermoanaerobacter, Carboxydothermus, etc. Members are nearly all predicted lipoproteins and belong to probable transport operons, some of which have been characterized as crucial to germination in response to alanine. Members typically have been gene symbols gerKC, gerAC, gerYC, etc.

Ger(x)C family spore germination protein such as Bacillus cereus spore germination protein GerLC, which contributes to the L-alanine germination response, and Bacillus subtilis spore germination protein B3, which is involved in the response to the mixture of L-asparagine, glucose, fructose and potassium ions
