  • Title: Chloramphenicol acetyltransferases specified by fi minus R factors.
    Author: Foster TJ, Shaw WV.
    Journal: Antimicrob Agents Chemother; 1973 Jan; 3(1):99-104. PubMed ID: 4597710.
    Abstract:
    Chloramphenicol acetyltransferases specified by fi(-) (F fertility-noninhibiting) R factors were compared with those specified by the fi(+) R factors R1, 222, and R6-S. Three classes of enzyme were distinguished: class I was determined by group N fi(-) R factors and was indistinguishable from the enzyme determined by fi(+) R factors, class II was correlated with group W fi(-) R factors, and class III was determined by R387, an unclassified fi(-) R factor.
