Effectors of protein activity
Z ring formation is inhibited upon binding of [protein|08EBBA57B807F8C27C37BEB275DF5E206935C698|mciZ] to FtsZ
bundling of FtsZ protofilaments into strikingly long and regular tubular structures reminiscent of eukaryotic microtubules requires the prior formation of large ring polymers of [protein|DB09F1C36257F511A84A083967A25A9D46744D14|sepF] [Pubmed|21224850]

FtsZ polymerization is inhibited by interaction with [protein|8C94C9598A823A8405B3E1FA0124E21D90845B8E|minC] [Pubmed|23577149]
Z ring formation requires [protein|953DE0F0B81894ECFF4C0693511AC238BF3D0C0A|pdhA] in a pyruvate-dependent manner [Pubmed|24825009]
GTPase activity is stimulated upon interaction with GpsB [pubmed|39602291]
