Synthesis and Regulation of Folate Coenzymes During early Germination in Vigna radiata
Pteridines, 2001 Folate profiles and DNA synthesis were studied during the early germinating period in Vigna radiata. Total folate andmethyl folate forms were increased from 4 to 32 hours during germination period studied.

Journal of Biological Chemistry, 2000 One-carbon metabolism is essential to provide activated one-carbon units in the biosynthesis of methionine, purines, and thymidylate. The major forms of folates in vivo are polyglutamylated derivatives.

Advanced Science, EarlyView.A zwitterionic asymmetric patch is developed via self‐induced phase separation. The cationic layer exhibits anti‐bacterial efficacy and releases pro‐healing factor, while the zwitterionic hydrogel prevents contamination and visceral adhesion. The strong mechanical interlocking of two layers leads to a high and stable burst pressure tolerance.

Frontiers in Immunology, 2017 Activation-induced cytidine deaminase (AID) and its relative APOBEC3 cytidine deaminases boost immune response by mutating immune or viral genes. Because of their genome-mutating activities, AID/APOBECs are also drivers of tumorigenesis.

On the origin and early evolution of biological catalysis and other studies on chemical evolution [PDF]
One of the lines of research in molecular evolution which we have developed for the past three years is related to the experimental and theoretical study of the origin and early evolution of biological catalysis. In an attempt to understand the nature of

Distribution of enzymes cleaving pyridine nucleotides in animal tissues [PDF]
, 1957 A number of enzymes capable of splitting the pyridine nucleotides have been found in animal tissues. A portion of the DPNase (1) that hydrolyzes the nicotinamide ribose bond of DPN and TPN was reported in the microsomes of rat liver (1).

Minimizing acetate formation in E. coli fermentations [PDF]
, 2007 Escherichia coli remains the best established production organisms in industrial biotechnology. However, during aerobic fermentation runs at high growth rates, considerable amounts of acetate are accumulated as by-product.

Journal of Biological Chemistry, 1967 Abstract The following evidence supports the conclusion that the reaction catalyzed by succinyl coenzyme A:3-keto acid coenzyme A transferase proceeds through two half-reactions in a "ping-pong" mechanism with an enzyme-CoA intermediate. (a) Double reciprocal plots of the initial rates against substrate concentration for the reaction in each direction ...

Identification and Application of a Novel Patulin Degrading Enzyme From Meyerozyma guilliermondii
Advanced Science, EarlyView.Patulin (PAT), a hazardous mycotoxin, threatens human health. A novel yeast‐derived short‐chain dehydrogenase/reductase effectively degrades PAT into nontoxic ascladiol via catalytic triad activity. The biological detoxification process has no significant effect on the quality of fresh pear juice.

Advanced Science, EarlyView.This study develops enucleated MSC‐derived microvesicles (Mito@euMVs) to deliver functional mitochondria for optimizing wound repair. By efficiently encapsulating mitochondria, Mito@euMVs rejuvenate hyperglycemia‐induced senescent fibroblasts and HUVECs. Using PVA microneedle patches, the therapeutic efficacy of Mito@euMVs is validated in diabetic rats
