Synteny mapping of abpA-srtB. S. cristatus AS1.3089 did not carry the abpA-srtB locus. ORFs flanking the abpA-srtB locus were deduced from genome sequences available at NCBI. All strains except S. cristatus AS1.3089, S. vestibularis F0396, and G. haemolysans M341 have been tested in vitro for the ability to bind amylase. Flanking genes include: (1) ribose-phosphate pyrophosphokinase; (2) aminotransferase; (3) haloacid dehalogenase; (4) MFS transporter; (5) peptidase M42; (6) peptidase; (7) DNA-binding transcriptional regulator, XRE-family; (8) metallophosphatase; (9) CoA-binding protein; and (10) IS200/IS605 family transposase.
