Mapping of functional sites on the primary structure of the contractile tail sheath protein of bacteriophage T4 by mutation analysis.

Abstract excerpt

In order to determine the functional roles of amino acid residues in gp18 (gp: gene product), the contractile tail sheath protein of bacteriophage T4, the mutation sites and amino acid replacements of available and newly created missense mutants with distinct phenotypes were determined. Amber mutants were also utilized for amino acid insertion by host amber suppressor cell strains. It was found that mutants that...
