Identification of a novel gene cluster participating in menaquinone (vitamin K2) biosynthesis. Cloning and sequence determination of the 2-heptaprenyl-1,4-naphthoquinone methyltransferase gene of Bacillus stearothermophilus.
Koike-Takeshita A, Koyama T, Ogura K. Koike-Takeshita A, et al. Among authors: koyama t. J Biol Chem. 1997 May 9;272(19):12380-3. doi: 10.1074/jbc.272.19.12380. J Biol Chem. 1997. PMID: 9139683 Free article.
Sequence analyses revealed the presence of three open reading frames (ORFs), designated as ORF-1, ORF-2, and ORF-3, and the structural genes of the heptaprenyl diphosphate synthase were proved to consist of ORF-1 (heps-1) and ORF-3 (heps-2) (Koike-Takeshita, A., Koyama, …

Intersubunit location of the active site of farnesyl diphosphate synthase: reconstruction of active enzymes by hybrid-type heteromeric dimers of site-directed mutants.
Koyama T, Gotoh Y, Nishino T. Koyama T, et al. Biochemistry. 2000 Jan 18;39(2):463-9. doi: 10.1021/bi991621b. Biochemistry. 2000. PMID: 10631008
Moreover, when a hybrid-type heterodimeric dimer of FPP synthase mutant subunits (R98E/F220A) was prepared, the FPP synthase activity was 18- and 390-fold of that of each of the almost inactive mutants as a dimeric enzymes, (R98E)(2) and (F220A)(2) [Koyama, T., et a …
