RT   and spore coat assembly.";
RL   Biosci. Biotechnol. Biochem. 75:1119-1128(2011).
CC   -!- FUNCTION: Spore protein involved in the assembly of several components
CC       of the spore coat, including CotB, CotG and CotH, and in spore
CC       germination. {ECO:0000269|PubMed:21670523}.
CC   -!- SUBCELLULAR LOCATION: Spore coat {ECO:0000305|PubMed:21670523}.
CC       Membrane {ECO:0000255}; Single-pass membrane protein {ECO:0000255}.
CC       Note=Accumulates in mature spores. {ECO:0000269|PubMed:21670523}.
CC   -!- DEVELOPMENTAL STAGE: Expressed during the later stages of sporulation.
CC       {ECO:0000269|PubMed:21670523}.
CC   -!- INDUCTION: Expression is regulated by the mother cell-specific
CC       transcription factors sigma K and GerE. {ECO:0000269|PubMed:21670523}.
CC   -!- DISRUPTION PHENOTYPE: Spores of the null mutant show partial lack of
CC       assembly of several coat components, including CotB, CotG and CotH, and
CC       impairment of response during germination.
CC       {ECO:0000269|PubMed:21670523}.
CC   -!- SIMILARITY: Belongs to the SscA family. {ECO:0000305}.
