This study aimed to compare the chromosomal beta-lactamase from
Pectobacterium versatile
, PEC-1, with the well-known and globally distributed TEM-1 in terms of genetic and functional properties. Despite the similarities between the enzymes, we obtained no definitive proof of gene transfer for the emergence of
