A 3-gene Cluster Containing a cell envelope protein, a protein kinase, and a phosphotransferase
This cluster contains at least three genes worth noting:
- The red genes numbered 1 are, according to Gary Olsen,
ATPase YjeE, predicted to have essential role in cell wall biosynthesis / COG3178:
Predicted phosphotransferase related to Ser/Thr protein kinases.
- The green genes numbered 2 seem to be a
Nucleotidyltransferase family protein.
- The blue genes numbered 3 are annotated as Organic solvent tolerance protein precursor.
Thus, we have a cluster relating to cell wall biosynthesis, perhaps.
It occurs in a number of spots throughout the Proteobacteria.
Note the occurrences of surA (numbered 4), which is believed to be
a periplasmic molecular chaperone protein facilitating correct folding and maturation of
outer membrane proteins in Gram-negative bacteria.
