From: Proteome analysis of serovars Typhimurium and Pullorum of Salmonella enterica subspecies I
Comparison of the protein expression of serovars Typhimurium (A and B) and Pullorum (C and D). The strains of serovar Pullorum expressed sulphate (Sbp) and thiosulphate binding protein (cysP) which were absent from the profile of Typhimurium. The enzyme cysteine synthase (cysK) was detected in the profile of both serovars but showed two fold higher expression in serovar Pullorum. The hypothetical oxidoreductase yghA was present in the profiles of serovar Typhimurium but absent from Pullorum. Mdh and gapA were present in all profiles and were used as reference spots in this comparison. The (x) symbols correspond to protein spots missing from the corresponding area of the gel.
