Since UmuD protein is proteolytically processed to an active form ( UmuD * ) in a RecA * - dependent fashion , and MucA shares extensive amino acid homology with UmuD , we examined whether MucA is similarly processed in the cell , using antiserum against a LacZ ' - ' MucA fusion protein .
 GENE: UmuD protein; GENE: UmuD *; GENE: RecA; GENE: MucA; GENE: UmuD; GENE: MucA; GENE: LacZ '; GENE: ' MucA
