We recently identified and characterized a novel broad substrate specificity amino acidracemase (BAR) from the hyperthermophilic archaeon Pyrococcus horikoshii OT-3.Three genes, PH0782, PH1423, and PH1501, encoding homologs exhibiting about45% seq...

A novel amino acid racemase with broad substrate specificity (BAR) was recently isolated from the hyperthermophilic archaeon Pyrococcus horikoshii OT-3. Characterization of this enzyme has been difficult, however, because the recombinant enzyme is...

2-Deoxy-d-ribose-5-phosphate aldolase (DERA) catalyzes the aldol reaction between two aldehydes and is thought to be a potential biocatalyst for the production of a variety of stereo-specific materials. A gene encoding DERA from the extreme haloph...

Amino Acids   Vol.47(No.8) 1579-1587   Aug 2015   [Refereed]
To date, there have been few reports analyzing the amino acid requirement for growth of hyperthermophilic archaea. We here found that the hyperthermophilic archaeon Pyrococcus horikoshii OT-3 requires Thr, Leu, Val, Phe, Tyr, Trp, His and Arg in t...
