The tyrosine phenol-lyase (TPL) gene of Citrobacter freundii was cloned and the complete nucleotide sequence of the TPL gene was determined. The TPL gene consists of 1368bp (456 amino acids). The deduced amino acid sequence of TPL was compared with t

The tryptophan synthase genes,trpA andtrpB, from a moderate thermophile,Bacillusstearothermophilus IFO13737, were expressed efficiently inEscherichiacoli. The recombinant tryptophan synthase amounted to 22% of the soluble cellular protein, and was pu

The tryptophan synthase genes, trpA and trpB, of Bacillus stearothermophilus IFO13737 were cloned by transformation of tryptophan auxotrophic mutations of the trp genes into Escherichia coli. The genes are located in the order of trpB and trp A, acco

Tryptophan synthase of Escherichia coli catalyzes the synthesis of l -cysteine from various β-substituted- l -alanines (e.g., l -serine) and sulfides (e.g., sodium hydrosulfide). Not only l -serine but also O- methyl- l -serine , O- acetyl- l -serin

Synthesis of S -carboxymethyl)- l -cysteine ( l -CMC) from L-serine with tryptophan synthase was studied. In the β-replacement reaction l -serine catalyzed by tryptophan synthase of Escherichia coli , thioglycolic acid was a poor substrate but alkyl
