The M. agalactiae 5632 strain contains an extended spma repertoire. Schematics representing the genomic organization of the spma loci in strains PG2 and 5632 (A) and the structural features of the corresponding spma gene products in both strains (B). In panel A, CDS corresponding to spma genes are filled in green. The S letter represents sequence corresponding to a signal peptide. Other CDSs conserved between PG2 and 5632 are filled by light yellow. Tracks of repeated nucleotides (Gn, where n is the number of residues) found before spma coding sequences are also indicated above the line. In panel B, predicted Spma proteins are represented schematically by large arrows beginning generally with a homologous amino-acid leader sequence (black boxes labelled S) followed by regions that have homology between spma gene products or that are repeated within the same product (blue dotted and grey boxes).
