analysis of proteins produced by minicells containing a plasmid demonstrated that the plasmid pyn87 , which can complement the nusa1 and amber mutations , codes for three bacterial proteins , a truncated nusa gene product ( 61 k ) , argg gene product ( 48 k ) and a 21 k dalton protein , and that the am4 mutation affects the synthesis of only nusa protein . lambda nam7 ( and lambda nam7nam53 ) phages could grow on these amber mutants at 32 degrees c but not on the parental strain .
