Design Notes
Simple repetition of the His codon most frequent in E. coli -- a more balanced codon-choice may be better.
There are two HIS codons: cat and cac;
In E.coli, cac seems preferred among highly expressed genes during exponential phase: 70%. Metabolic proteins have about even numbers of the two codons.
