MipZ is an ATPase that forms a complex with the chromosome partitioning protein ParB near the chromosomal origin of replication [1]. It is responsible for the temporal and spatial regulation of FtsZ ring formation [1]. [1]. 16839883. MipZ, a spatial regulator coordinating chromosome segregation. with cell division in Caulobacter..

This is a family of bacterial proteins involved in cellulose biosynthesis. (Roemling U. and Galperin M.Y. "Bacterial cellulose biosynthesis. Diversity of operons and subunits" (manuscript in preparation)). A second component of the extracellular matrix of the multicellular morphotype (rdar) of Salmonella typhimurium and Escherichia coli is cellulose. The family does contain a P-loop sequence motif suggesting a nucleotide binding function, but this has not been confirmed. [1]. 11260463. The multicellular morphotypes of Salmonella typhimurium and.

This family contains ATPases involved in plasmid partitioning [1]. It also contains the cytosolic Fe-S cluster assembling factor NBP35 which is required for biogenesis and export of both ribosomal subunits [2]. [1]. 2149583.

This family consists of various cobyrinic acid a,c-diamide synthases. These include CbiA Swiss:P29946 and CbiP Swiss:Q05597 from S.typhimurium [4], and CobQ Swiss:Q52686 from R. capsulatus [3]. These amidases catalyse amidations to various side chains of hydrogenobyrinic acid or cobyrinic acid a,c-diamide in the biosynthesis of cobalamin (vitamin B12) from uroporphyrinogen III. Vitamin B12 is an important cofactor and an essential nutrient for many plants and animals and is primarily produced by bacteria [4]. The family also contains dethiobiotin synthetases as well as the plasmid partitioning proteins of the MinD/ParA family [6]. [1]. 9742225.
