标 题 :Synthesis of sialic acid and synthetic intermediate therefor
发明人：SHIBA TETSUO; TESHIMA TADASHI; YAMAMOTO TOSHIHIRO
权利人:KANTO ISHI PHARMA CO LTD
摘要:An efficient synthesis of sialic acid (N-acetylneuramic acid) useful as the starting material of medicines, a synthetic intermediate therefor, isosialic acid as an isomer of sialic acid, synthesis thereof, and a synthetic intermediate therefor. Sialic acid is synthesized from D-glucose and oxaloacetic acid through the intermediates (Ia) and (IIIa), while isosialic acid represented by formula (IV) is synthesized from an isomer of the intermediate (Ia).

摘要:An object of the present invention is to identify an enzyme having activity of synthesizing dihydrotentoxin that is a tentoxin precursor and an enzyme having activity of synthesizing tentoxin using dihydrotentoxin as a substrate. The present invention concerns a tentoxin synthesis-related gene encoding a protein comprising the amino acid sequence of SEQ ID NO: 16 and having activity of nonribosomal peptide synthesis of dihydrotentoxin and a tentoxin synthesis-related gene encoding a protein comprising the amino acid sequence of SEQ ID NO: 18 and having activity of converting dihydrotentoxin to tentoxin.
