Abstract

Summary: Chloramphenicol acetyl transferase (CAT) was purified from K12 carrying R1 and 222 and from K12 (R1 Cm /R100-99 TcCm). The third enzyme has a lower affinity for chloramphenicol and greater heat lability than those specified by R1 and 222, compatible with the enzyme's resulting from interallelic complementation. CAT has a molecular weight of 80000, with subunits of 20000. Material cross reacting with anti-222 CAT serum was detected in Cm mutant cell sonicates.
