    Here we present an optimized procedure to generate amino acid variations at specific site(s) of proteins, followed by a simple one-step screen for mutants with the desired beta-glucosidase activity. The procedure was evaluated by introducing sequence variation into a codon specifying a non-functional variant of the catalytic nucleophile (E401) of the maize beta-glucosidase Zm-p60.1. Observed and theoretically expected frequencies of the four possible variants of the codon and the two possible phenotypes (functional and non-functional) were investigated. Deviations in codon and phenotype frequencies were expressed as a coefficient. This coefficient was then used to estimate the extent of over-sampling, of the mutant library, which would be necessary to compensate for the underrepresentation of some sequences.
