BbCRASP-encoding genes in the genome of B. burgdorferi strain B31. The segmented genome of B. burgdorferi B31 is composed of a linear main chromosome and at least 24 other linear and circular replicons (Fraser et al., 1997; Casjens et al., 2000; Miller et al., 2000a). Several publications have referred to BbCRASP-encoding genes of the strain B31 by the open reading frame (ORF) numbers assigned following sequencing and annotation of the genome (Casjens et al., 2000). The sequenced B31 subculture had lost cp32-2, cp32-5, and other DNAs, so not all genes known to exist in strain B31 were given ORF numbers. BbCRASP-1 is encoded by cspA (ORF BBA68) gene located on the linear DNA element lp54. BbCRASP-2 is encoded by cspZ (ORF BBH06) carried by another linear replicon, lp28-3. Genes erpP (ORF BBN38, encoding BbCRASP-3) and erpC (encoding BbCRASP-4) are carried by plasmids cp32-9 and cp32-2, respectively. Strain B31 can contain three identical copies of erpA, encoding BbCRASP-5, on prophages cp32-1 (ORF BBP38), cp32-5, and cp32-8 (ORF BBL39).
