Protein
Sporulation-specific cell division protein SsgB
Organism
Saccharopolyspora erythraea (strain ATCC 11635 / DSM 40517 / JCM 4748 / NBRC 13426 / NCIMB 8594 / NRRL 2338)
Function
Involved in sporulation-specific cell division (PubMed:19567872). Required for early stages of sporulation. Important in the process of growth cessation prior to sporulation-specific cell division. Recruits cell division protein FtsZ to the future septum sites and tethers the contractile ring structure (Z ring) to the cytoplasmic membrane during sporulation. Stimulates polymerization and filament length of FtsZ in vitro (By similarity).
Similarity
Belongs to the SsgA family.
