SpoVB is the stage V sporulation protein B of the bacterial endopore formation program in Bacillus subtilis and various other Firmcutes. It is nearly universal among endospore-formers. Paralogs with rather high sequence similarity to SpoVB exist, including YkvU in B. subtilis and a number of proteins in the genus Clostridium. [Cellular processes, Sporulation and germination]
