Polyphenol Oxidase Products Are Priming Agents for LPMO Peroxygenase Activity
ChemSusChem, Volume 16, Issue 18, September 22, 2023., 2023 Priming versus fueling. It is demonstrated here that the catalytic products of a polyphenol oxidase acting on guaiacol can prime the peroxygenase activity of lytic polysaccharide monooxygenase (LPMO) towards cellulose in H2O2‐driven reactions but do not provide sufficient reducing power to fuel LPMO activity under O2‐driven reactions.

European Journal of Inorganic Chemistry, Volume 2022, Issue 35, December 16, 2022., 2022 Dinuclear copper(I) complexes supported by bis‐tridentate N‐donor ligands with two imine functions mediate the conversion of a monophenol to its corresponding o‐quinone, in contrast to analogous complexes supported by ligands with amine functions. Abstract Four structurally related bis‐tridentate N‐donor ligands with either two secondary amine or two ...

Bacterial pigments: A colorful palette reservoir for biotechnological applications
Biotechnology and Applied Biochemistry, Volume 69, Issue 3, Page 981-1001, June 2022., 2022 Abstract Synthetic derivatives are currently used instead of pigments in many applicative fields, from food to feed, from pharmaceutical to diagnostic, from agronomy to industry. Progress in organic chemistry allowed to obtain rather cheap compounds covering the whole color spectrum. However, several concerns arise from this chemical approach, as it is

The Plant Genome, Volume 15, Issue 2, June 2022., 2022 Abstract As one of the important species belonging to the Bletilla genus of Orchidaceae, Bletilla striata (Thunb.) Rchb. f., possesses both ornamental and medicinal values. Its dried tubers are used as a traditional Chinese medicine, and several secondary metabolites have been indicated to be the active ingredients.

ChemBioChem, Volume 23, Issue 6, March 18, 2022., 2022 The ability to perform regiospecific hydroxylations of sterically challenging monophenols was engineered into a flavin‐dependent monooxygenase. Its variants are valuable tools for production of the corresponding catechols for in vitro or live whole‐cell conversions.

Anthropogenic and natural barriers affect genetic connectivity in an Alpine butterfly
Molecular Ecology, Volume 30, Issue 1, Page 114-130, January 2021., 2021 Abstract Dispersal is a key biological process serving several functions including connectivity among populations. Habitat fragmentation caused by natural or anthropogenic structures may hamper dispersal, thereby disrupting genetic connectivity. Investigating factors affecting dispersal and gene flow is important in the current era of anthropogenic ...

티로시나아제 반응을 이용한 수용성 멜라닌 합성 및 효소 코팅 [PDF]
, 2022 학위논문(박사) -- 서울대학교대학원 : 공과대학 화학생물공학부, 2022. 8. 김병기.생활성이 있는 나노 물질의 합성은 점점 가속화된 관심을 받고있는 분야이다. 나노 물질 합성은 물리, 화학, 생물적 합성법이 알려져있다. 나노물질은 일반적으로 크기, 물리화학적 성질의 조절에따라 응용 방식이 결정된다. 효소적 합성 방식은 앞선 2가지 방식에 비해서 균질하지 못한 입자의 생산 방식으로 알려져 있어, 반응에 대한 심층적인 분석이 어려웠다.
