The generation of NADPH by malic enzyme (ME) was postulated to be a rate-limiting step during fatty acid synthesis in oleaginous fungi, based primarily on the results from research focusing on ME in Mucor circinelloides. This hypothesis is challenged by a recent study showing that leucine metabolism, rather than ME, is critical for fatty acid synthesis in M. circinelloides. To clarify this, the...
The oil-producing fungus Mortierella alpina 1S-4 is an industrial strain. In order to prepare host strains for a transformation system for this fungus, six uracil auxotrophs were obtained by means of random mutation with N-methyl-N'-nitro-N-nitrosoguanidine (MNNG). When the activities of orotate phosphoribosyl transferase (OPRTase, EC 2.4.2.10) and orotidine-5'-phosphate decarboxylase (OMPdecas...
Molecular cloning of the gene encoding sterol Delta7 reductase from the filamentous fungus Mortierella alpina 1S-4, which accumulates cholesta-5,24-dienol (desmosterol) as the main sterol, revealed that the open reading frame of this gene, designated MoDelta7SR, consists of 1,404 bp and codes for 468 amino acids with a molecular weight of 53,965. The predicted amino acid sequence of MoDelta7SR ...
The enzymes that are involved in the elongation of fatty acids differ in terms of the substrates on which they act. To date, the enzymes specifically involved in the biosynthesis of polyunsaturated fatty acids have not yet been identified. In an attempt to identify a gene(s) encoding an enzyme(s) specific for the elongation of gamma-linolenic acid (GLA) (18:3n-6), a cDNA expression library was ...
