Characterization of anAspergillus nidulansL-arabitol dehydrogenase mutant

Autor: Michel Flipphi, Jaap Visser, Ronald P. de Vries, C.F.B. Witteveen

Publikováno v: FEMS Microbiology Letters. 123:83-90

The degradation pathway for L-arabinose, which consists of a sequence of alternating reduction and oxidation reactions prior to ultimate phosphorylation, was studied in Aspergillus nidulans wild-type as well as in an L-arabinose non-utilizing mutant.

Publikováno v: Current Genetics. 24:408-416

The induction of glucose oxidase, catalase, and lactonase activities was studied both in wild-type and in glucose oxidase regulatory and structural mutants of Aspergillus niger. The structural gene for glucose oxidase was isolated and used for Northe

Glycerol catabolism in Aspergillus nidulans

Autor: D.H.A. Hondmann, C.F.B. Witteveen, R. Busink, Jantien Visser

Publikováno v: Journal of general microbiology 137 (1991)
Journal of general microbiology, 137, 629-636

Glycerol is catabolized in Aspergillus nidulans by glycerol kinase and a mitochondrial FAD-dependent sn-glycerol 3-phosphate dehydrogenase. The levels of both enzymes are controlled by carbon catabolite repression and by specific induction. Biochemic

Polyol pools in Aspergillus niger

Autor: Jaap Visser, C.F.B. Witteveen

Publikováno v: FEMS Microbiology Letters 134 (1995)
FEMS Microbiology Letters, 134, 57-62

The accumulation and excretion of polyols was investigated under various growth conditions and at different stages of the life cycle of Aspergillus niger. Glycerol was found to be the major solute in osmotic adjustment of the hyphae. Conidiospores co

Isolation and characterization of two xylitol dehydrogenases from Aspergillus niger

Autor: Jaap Visser, C.F.B. Witteveen, Frans Weber, R. Busink

Publikováno v: Microbiology, 140, 1679-1685
Microbiology 140 (1994)

An NADPH-dependent L-xylulose reductase [xylitol:NADP 4-oxidoreductase; EC 1.1.1.10 (LXDH)] from Aspergillus niger was purified and characterized. It is an octamer with a monomeric molecular mass of 32 kDa, showing high specificity for L-xylulose, xy

The subcellular localization of glucose oxidase (EC 1.1.3.4) in Aspergillus niger N400 (CBS 120.49) was investigated by (immuno)cytochemical methods. By these methods, the bulk of the enzyme was found to be localized in the cell wall. In addition, fo

Current Genetics, 18, 435-439

A number of mutants of Aspergillus niger, affected in glucose oxidase (GOX) expression, are described. The overproducing mutants could be classified into seven complementation groups whereas two glucose oxidase-negative complementation groups were re
