epsilon(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 epsilon(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.
ε(34)是一种转化噬菌体,它能使E群沙门氏菌中的O抗原发生糖基化,从而产生抗原34。尿苷二磷酸葡萄糖是抗原34的前体,糖基脂质是这一过程中的必需中间体。已分离出不能产生抗原34的ε(34)突变体。携带这些突变体的溶原性细胞有两种类型。1型突变体溶原菌不能形成糖基脂质中间体;2型溶原菌能形成糖基脂质,但不能将脂质中的葡萄糖转移到O抗原上。
