  • a The number of copies of each IS element is indicated in parentheses. An asterisk indicates that the element contains a frameshift and/or a premature stop. NP, no IS elements present; ND, not determined (multiple IS elements have been identified in pCOO, but most of them are not grouped with the pE24377A plasmids).
