BtubAB
BtubAB refers to a specific gene or gene product found in bacteria, particularly within the context of cell division. This gene is part of the tubulin family of proteins, which are essential for forming microtubules. In bacteria, these tubulin-like proteins, often referred to as FtsZ proteins, play a critical role in the formation of the Z-ring, a dynamic structure that constricts to divide the bacterial cell. The designation "BtubAB" suggests it is a member of this bacterial tubulin family, with "Btub" likely standing for bacterial tubulin and "AB" indicating specific subunits or isoforms.
The FtsZ protein, as represented by BtubAB, polymerizes into a ring at the midcell of a dividing
