Induction of glucose oxidase, catalase, and lactonase in Aspergillus niger

Current Genetics, 1993
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 Northern analysis and in transformation experiments using various gox mutations.

[6] Catabolism of uronate and aldonate: Lactonases

1970
Publisher Summary In this chapter, the separation of aldonolactonase and 6-phosphogluconolactonase is performed. Aldonolactonase shows hydrolyzing activity against L -dehydroascorbic acid. The procedure for separation described in the chapter is suitable for a large-scale preparation of this enzyme.

Engineering of Extremophilic Phosphotriesterase-Like Lactonases for Biotechnological Applications

2016
Organophosphate compounds, as most pesticides and chemical warfare agents, first appeared in the US after 1930s and became widespread after World War II. At present, enzymatic detoxification of organophosphate compounds represents an important issue worldwide, due to their permanent and excessive use that has led in many places to the contamination of ...

Studies on the glucono-δ-lactonase of Psudomonas fluorescens

Biochimica et Biophysica Acta, 1960
Abstract The first stage of the oxidative metabolism of d -glucose by Pseudomonas fluorescens is the conversion of d -glucopyranose into d -glucono-δ-lactone. This lactone is hydrolysed to gluconic acid by an enzyme found in the soluble fraction of cell-free extracts of the bacterium. the lactonase has been purified a hundredfold and some of its
