Patent ID: 7517678

Claim:
A method for producing a transaminase protein encoded by a transaminase gene comprising culturing E. coli , into which the transaminase gene has been introduced, in the temperature range equal to or higher than 44° C. and lower than 47° C. after introduction of expression of the transaminase gene, wherein the transaminase gene is selected from the group consisting of the transaminase gene APE2248 as set forth in SEQ ID NO:1 of hyperthermophile Aeropyrum pernix , the transaminase gene PH1423 as set forth in SEQ ID NO:6 of hyperthermophile Pyrococcus horikoshii , the transaminase gene APE0457 as set forth in SEQ ID NO: 9 of hyperthermophile Aeropyrum pernix , and the transaminase gene ST1225 as set forth in SEQ ID NO:12 of hyperthermophile Sulfolobus tokodait.
