Cell division protein FtsL; Essential cell division protein. May link together the upstream cell division proteins, which are predominantly cytoplasmic, with the downstream cell division proteins, which are predominantly periplasmic.

Outer membrane protein maturation factor peptidyl-prolyl cis-trans isomerase SurA; Chaperone involved in the correct folding and assembly of outer membrane proteins. Recognizes specific patterns of aromatic residues and the orientation of their side chains, which are found more frequently in integral outer membrane proteins. May act in both early periplasmic and late outer membrane-associated steps of protein maturation.

2-C-methyl-D-erythritol 4-phosphate cytidylyltransferase IspD; Catalyzes the formation of 4-diphosphocytidyl-2-C-methyl-D- erythritol from CTP and 2-C-methyl-D-erythritol 4-phosphate (MEP).

Stringent starvation protein b SspB.

Beta barrel protein translocation component BamE; Part of the outer membrane protein assembly complex, which is involved in assembly and insertion of beta-barrel proteins into the outer membrane.

DNA repair protein RecO; Involved in DNA repair and RecF pathway recombination.

DNA polymerase III delta subunit HolA.

Outer membrane lipoprotein carrier protein LolA; Participates in the translocation of lipoproteins from the inner membrane to the outer membrane. Only forms a complex with a lipoprotein if the residue after the N-terminal Cys is not an aspartate (The Asp acts as a targeting signal to indicate that the lipoprotein should stay in the inner membrane).

Cell wall structural complex component MreD; Involved in formation of the rod shape of the cell. May also contribute to regulation of formation of penicillin-binding proteins. Belongs to the MreD family.
