SDS-polyacrylamide gel analysis of P22-infected Salmonella has allowed identification of the c2 repressor (MW 31,000) and study of repressor synthesis in regulatory mutants of P22. Repressor is synthesized in reduced amounts or is absent in infections with P22, clNo.7, P22, c2 am08, P22 c3 am03, and P22 c3 am012, but is synthesized in markedly increased amounts in the virulent mutant, P22 virB3, and its component mutants, vx and k5. Higher levels of repressor are also found in the P22 cly 17 mutant.
对感染P22的沙门氏菌进行十二烷基硫酸钠-聚丙烯酰胺凝胶分析，已鉴定出c2阻遏蛋白（分子量31,000），并对P22调控突变体中的阻遏蛋白合成进行了研究。在感染P22、clNo.7、P22、c2 am08、P22 c3 am03和P22 c3 am012时，阻遏蛋白合成量减少或缺失，但在毒性突变体P22 virB3及其组成突变体vx和k5中，阻遏蛋白合成量显著增加。在P22 cly 17突变体中也发现了更高水平的阻遏蛋白。
