• a The percent identity of each sequence to six consensus-type β turns was calculated according to the method of Hutchinson and Thornton (18). Values are shown only for the most relevant types of β turns. Values in parentheses were calculated for the K11E (relevant for the -G10-K11-H12-S13- sequence) and N5K (relevant for the other sequences) substitution mutants.
