Enzymatic conversion of norsolorinic acid to averufin in aflatoxin biosynthesis
TLDR
Results indicate that the reaction sequence NA in equilibrium AVN----HAVN----AVR is involved in the biosynthetic pathway of aflatoxins. Expand
Simple method for screening aflatoxin-producing molds by UV photography
TLDR
Results indicate that the UV photography technique can be used as a simple, safe, and rapid method of screening aflatoxin-producing molds. Expand
Two distinct O-methyltransferases in aflatoxin biosynthesis
TLDR
Results of the cell-free experiment with S-adenosyl-[methyl-3H]methionine showed that these O-methyltransferases were different in their protein molecules and were involved in both the reactions from DMST to OMST and DHDMST to DHOMST. Expand
Biosynthetic relationship among aflatoxins B1, B2, G1, and G2
TLDR
The feeding experiments of strain NIAH-26 and similar feeding experiments in which 27 kinds of mutants including these mutants were used, suggest that the same enzymes may be involved in the both biosynthetic pathways from ST to AFB1- AFG1 and DHST to AFB2-AFG2. Expand
A metabolic grid among versiconal hemiacetal acetate, versiconol acetate, versiconol and versiconal during aflatoxin biosynthesis.
TLDR
Results indicate that a metabolic grid catalysed by dehydrogenase and esterase among VHA, VOAc, VOH and VHOH, and a reaction from VHoh to VC (VB) are involved in aflatoxin biosynthesis. Expand
C20-C24 monounsaturated fatty acid isomers in the lipids of flathead flounder, Hippoglossoides dubius
Compositions of 20:1 and 22:1 isomers in the lipids of flathead flounder, Hippoglossoides dubius, fillets without skin were determined by open-tubular GLC of methyl esters and GC-MS of their dimethylExpand
Changes in positional distribution of fatty acids in dorsal muscle triacyl-sn-glycerols from chum salmon, Oncorhynchus keta, at spawning season
TLDR
The uneven depletion of TGs was found to depend on the position in which the fatty acids are esterified, and the view that the depletion occurred unevenly during the migration from coast to upstream was confirmed. Expand
Japanese Sardine Oil as a Source of 16:3(n-4) and 16:4(n-l) Fatty Acids
Open tubular gas liquid Chromatographic (GLC) analysis of fatty acids in Japanese sardine oil showed the contents of 1.57% hexadecatrienoic acid (16:3) and 2.55% hexadecatetraenoic acid (16:4).Expand
Stereochemistry during aflatoxin biosynthesis: conversion of norsolorinic acid to averufin
TLDR
The results indicate that the enzymes involved in this pathway show strict stereospecificity to their substrates and that the configuration of (1'S,5'R)-AVR leading to the formation of aflatoxins is due to the stereos pecificity of NA dehydrogenase which catalyzes the reaction between ( 1'S)-AVN and NA.
