Inner membrane protein, SpoIIIJ; Required for the insertion and/or proper folding and/or complex formation of integral membrane proteins into the membrane. Involved in integration of membrane proteins that insert both dependently and independently of the Sec translocase complex, as well as at least some lipoproteins. Aids folding of multispanning membrane proteins (By similarity).

Tryptophan synthase alpha chain; The alpha subunit is responsible for the aldol cleavage of indoleglycerol phosphate to indole and glyceraldehyde 3-phosphate. Belongs to the TrpA family.

Sortase (surface protein transpeptidase), YHCS B.subtilis ortholog.

Tryptophan synthase beta chain; The beta subunit is responsible for the synthesis of L- tryptophan from indole and L-serine.

Autolytic lysozime (1,4-beta-N-acetylmuramidase), family 25 of glycosyl hydrolases; peptodoglycan-binding domain.

RNA polymerase-associated protein RpoZ, omega subunit (YLOH B.subtilis ortholog); Promotes RNA polymerase assembly. Latches the N- and C- terminal regions of the beta' subunit thereby facilitating its interaction with the beta and alpha subunits.

Sporulation specific penicillin-binding protein.

Flavoprotein involved in panthothenate metabolism, YLOI B.subtilis ortholog; Catalyzes two steps in the biosynthesis of coenzyme A. In the first step cysteine is conjugated to 4'-phosphopantothenate to form 4- phosphopantothenoylcysteine, in the latter compound is decarboxylated to form 4'-phosphopantotheine; In the C-terminal section; belongs to the PPC synthetase family.

Maf protein ortholog, putative inhibitor of septum formation; Nucleoside triphosphate pyrophosphatase that hydrolyzes dTTP and UTP. May have a dual role in cell division arrest and in preventing the incorporation of modified nucleotides into cellular nucleic acids.
