Order of dcw cluster proteins in V.spinosum as compared to those of selected reference bacteria . The key to one letter gene symbols are as follows : R, mraZ; M, mraW; L, ftsL; I, ftsI; E, murE; F, murF; Y, mraY; D, murD; W, ftsW; G, murG; C, murC; B, murB; d, ddlB; Q, ftsQ; A, ftsA; Z, ftsZ; V, envA(lpxC). Full species names are E.coli, Escherichia coli; B.subtilis, Bacillus subtilis; C.trachomatis, Chlamydia trachomatis; T.maritima, Thermotoga maritima; V.spinosum, Verrucomicrobium spinosum. '+' symbols represent a homologue is present at a different location within the genome, '-' symbols represent no recognizable homologue found and is only used where complete genome sequences are available, '?' symbols indicate a possible homologue. It should be noted that although genes are often shown as if contiguous, in some cases genes are separated from the next downstream e.g. in C. trachomatis, murE is separated from murF. Also, some genes are actually contiguous but a + sign intervenes only to indicate that a homolog missing in an expected position in between them is present but in another part of the genome.
