Recessive osteogenesis imperfecta caused by LEPRE1 mutations: clinical documentation and identification of the splice form responsible for prolyl 3-hydroxylation [PDF]

open access: yes, 2009
: Background: Recessive forms of osteogenesis imperfecta (OI) may be caused by mutations in LEPRE1, encoding prolyl 3-hydroxylase-1 (P3H1) or in CRTAP, encoding cartilage associated protein.

Biotransformation of Isoflavone Using Enzymatic Reactions

open access: yesMolecules, 2013
The roles of cytochrome P450 monooxygenases (CYPs) from Streptomyces spp. which are called the “treasure islands” for natural products for medicine and antibiotics are not well understood.

Efficient hydroxylation of flavonoids by using whole-cell P450 sca-2 biocatalyst in Escherichia coli

open access: yesFrontiers in Bioengineering and Biotechnology, 2023
The hydroxylation is an important way to generate the functionalized derivatives of flavonoids. However, the efficient hydroxylation of flavonoids by bacterial P450 enzymes is rarely reported.

Designed whole-cell-catalysis-assisted synthesis of 9,11-secosterols

open access: yesBeilstein Journal of Organic Chemistry, 2021
A method for the synthesis of 9,11-secosteroids starting from the natural corticosteroid cortisol is described. There are two key steps in this approach, combining chemistry and synthetic biology.

A Novel Antimalarial Metabolite in Erythrocyte From the Hydroxylation of Dihydroartemisinin by Cunninghamella elegans

open access: yesFrontiers in Chemistry, 2022
Dihydroartemisinin (DHA) is a sesquiterpene endoperoxide with prominent antimalarial efficacy, which was discovered by Professor Youyou Tu through the reduction of artemisinin in the 1970s.

Biocatalytic hydroxylation of n-butane with in situ cofactor regeneration at low temperature and under normal pressure

open access: yesBeilstein Journal of Organic Chemistry, 2012
The hydroxylation of n-alkanes, which proceeds in the presence of a P450-monooxygenase advantageously at temperatures significantly below room temperature, is described.

Hydroxylation Kinetics of Epoxidized Tung Oil Using Methanol as Nucleophilic Agent

open access: yesInternational Journal of Technology, 2023
The synthesis of vegetable oil-based polyols has been carried out through the epoxidation-hydroxylation process. However, Tung oil has never been explored in the process, even though Tung oil has a high double bond.

Degradation of contaminants of emerging concern by UV/H2O2 for water reuse: Kinetics, mechanisms, and cytotoxicity analysis. [PDF]

open access: yes, 2020
Advanced oxidation using UV and hydrogen peroxide (UV/H2O2) has been widely applied to degrade contaminants of emerging concern (CECs) in wastewater for water reuse. This study investigated the degradation kinetics of mixed CECs by UV/H2O2 under variable
