摘要：

Germination of Bacillus subtilis spores via the GerA nutrient receptor was suppressed by GerAC lacking the diacylglycerylated cysteine essential for receptor function. Overexpression of the C protein of the GerB nutrient receptor also suppressed the function of both the GerA receptor and a variant GerB receptor, GerB*. These findings suggest that GerAC and GerBC interact with their respective A and B proteins in GerA or GerB receptors and that GerBC potentially interacts with GerAA-GerAB. However, GerAC did not appear to interact with GerBA-GerBB.
