Results Isolation of fliA * mutants resistant to inhibition by FlgM Models for negative regulation of s28 by FlgM predict a direct , potentially multipartite , interaction between the two proteins .39,40 To identify amino-acid-residues of s28 , we carried out a selection for ¯ iA mutants defective for negative regulation by ¯ iA * mutan .
