“…Although some DAOZ genes have been cloned and sequenced (Fukui et al, 1987;Furuya & Matsuda, 1993;Isogai et a/., 1990;Jacobs et al, 1987;Momoi et al, 1988Momoi et al, , 1990Tada et al, 1990), only four enzymes have been isolated to homogeneity, i.e. those from pig kidney (Jacobs et al, 1987), Rhodotorula gracilis (Rhodosporidium toruloides) (Pilone et al, 1987), Trigonopsis variabilis (Pollegioni et al, 1993) and Fusarium solani (Isogai et al, 1990).…”
