Molecular cloning in yeast by in vivo homologous recombination of the yeast putative alpha1 subunit of the voltage-gated calcium channel.

abstract：:The two tryptophan residues, Trp-248 and Trp-330, in tryptophan indole-lyase (tryptophanase) from E. coli have been separately mutated to phenylalanine using site-directed mutagenesis. Both single tryptophan mutant enzymes have full catalytic activity, but exhibit different fluorescence and near-UV circular dichroism ...
