Abstract
ε 34 Is a converting bacteriophage which brings about a glucosylation of the O antigen in the E group salmonella, thus producing antigen 34. Uridine diphosphate glucose is the precursor of antigen 34 and a glucosyl-lipid is an essential intermediate in this process. Mutants of ε 34 which cannot produce antigen 34 have been isolated. Cells lysogenic for these mutants are of two types. Type 1 mutant lysogens cannot form the glucosyl-lipid intermediate; those of type 2 can form glucosyl-lipid but are unable to transfer glucose from the lipid to the O antigen.Keywords
