FIG 2.
Effects of temperature and chaperones on phage growth of N-arm and P-domain coat protein mutants. The key for each mutant is included in the figure. (A) Efficiency of plating of the coat protein mutants. (B) Efficiency of plating in the presence or absence of GroES/L for coat protein E5A and D14A variants. Substitutions are indicated in the graphs; − or + signs represent the absence or presence of excess GroES/L, respectively. The reversion frequency of the 5− amber phage was between 10−7 and 10−5.
