Use of chitin and chitosan to produce new chitooligosaccharides by chitinase Chit42: enzymatic activity and structural basis of protein specificity
(BioMed Central, 2018)
Background Chitinases are ubiquitous enzymes that have gained a recent biotechnological attention due to their ability to transform biological waste from chitin into valued chito-oligomers with wide agricultural, ...

Controlled Transcription of Regulator Gene carS by Tet-on or by a Strong Promoter Confirms Its Role as a Repressor of Carotenoid Biosynthesis in Fusarium fujikuroi
(MDPI, 2020-12)
Carotenoid biosynthesis is a frequent trait in fungi. In the ascomycete Fusarium fujikuroi, the synthesis of the carboxylic xanthophyll neurosporaxanthin (NX) is stimulated by light. However, the mutants of the carS gene, ...

Identification and regulation of fusA, The polyketide synthase gene responsible for fusarin production in Fusarium fujikuroi
(American Society for Microbiology, 2012)
Fusarins are a class of mycotoxins of the polyketide family produced by different Fusarium species, including the gibberellin- producing fungus Fusarium fujikuroi. Based on sequence comparisons between polyketide synthase ...

Analysis of al-2 mutations in neurospora
(Public Library of Science, 2011)
The orange pigmentation of the fungus Neurospora crassa is due to the accumulation of the xanthophyll neurosporaxanthin and precursor carotenoids. Two key reactions in the synthesis of these pigments, the formation of ...

A global perspective on carotenoids: metabolism, biotechnology, and benefits for nutrition and health.
(Elsevier, 2018-04-04)
Carotenoids are lipophilic isoprenoid compounds synthesized by all photosynthetic organisms and some non-photosynthetic bacteria and fungi. With some notable exceptions, animals (including humans) do not produce carotenoids ...

Comparative transcriptomic analysis unveils interactions between the regulatory CarS protein and light response in Fusarium
(BMC, 2019)
Background The orange pigmentation of the agar cultures of many Fusarium species is due to the production of carotenoids, terpenoid pigments whose synthesis is stimulated by light. The genes of the carotenoid pathway and ...

A novel lncRNA as a positive regulator of carotenoid biosynthesis in Fusarium
(Nature Research, 2020)
The fungi Fusarium oxysporum and Fusarium fujikuroi produce carotenoids, lipophilic terpenoid pigments of biotechnological interest, with xanthophyll neurosporaxanthin as the main end product. Their carotenoid biosynthesis ...

A RALDH-like enzyme involved in Fusarium verticillioides development
(Elsevier, 2016)
Retinaldehyde dehydrogenases (RALDHs) convert retinal to retinoic acid, an important chordate morphogen. Retinal also occurs in some fungi, such as Fusarium and Ustilago spp., evidenced by the presence of rhodopsins and ...

Neurosporaxanthin overproduction by Fusarium fujikuroi and evaluation of its antioxidant properties
(Multidisciplinary Digital Publishing Institute (MDPI), 2020)
Neurosporaxanthin (NX) is a carboxylic carotenoid produced by some filamentous fungi, including species of the genera Neurospora and Fusarium. NX biosynthetic genes and their regulation have been thoroughly investigated ...
