Variation in mitochondrial NADH dehydrogenase subunit 5 (ND5) and NADH dehydrogenase subunit 4 (ND4) genes was surveyed in Triatoma infestans from 24 localities of Argentina. The DNA sequence comparisons of 2,183 basepairs of the mitochondrial genome, which include the complete sequence of ND5 (1,712 basepairs) and 401 basepairs of ND4 genes, showed 19 haplotypes determined by 48 variable sites and a nucleotide diversity value of 0.292%. Twenty-six (65%) substitutions were synonymous, and there were 14 (35%) predicted amino acid replacements in ND5. In ND4, 5 (62.5%) substitutions were synonymous and 3 (37.5%) were replacement sites. Samples from six localities studied shared one haplotype and the rest of the localities had different haplotypes. The amplified regions should be useful for population genetic studies.

Phenylketonuria (PKU) is characterized by an autosomal recessive mutation in the phenylalanine hydroxylase (PAH) gene. Impaired PAH enzyme activity leads to the accumulation of phenylalanine (Phe) and its metabolites in the bloodstream, which disrupts the central nervous system and causes psychomotor retardation. Early diagnosis of PKU is essential for timely intervention.

As a marker of human metabolism, acetone is important for lipid metabolism monitoring and early detection of diabetes. In this study, we developed a handheld biosensor for acetone based on fluorescence detection by utilizing the enzymatic reaction of secondary alcohol dehydrogenase (S-ADH) with β-nicotinamide adenine dinucleotide (NADH, = 340 nm, = 490 nm). In the reaction, NADH is oxidized when acetone is reduced to 2-propanol by S-ADH, and the acetone concentration can be measured by detecting the amount of NADH consumed in this reaction.

Gossypol removal is crucial for the resourceful utilization of cottonseed meals in the food and feed industries. Herein, we investigated the comprehensive detoxification mechanism of a gossypol-tolerant strain of (WK331) newly isolated from the rumen. Biodegradation assays showed that WK331 removes over 80% of free gossypol, of which 50% was biodegraded and 30% was converted into bound gossypol.

7β-Hydroxysteroid dehydrogenase (7β-HSDH) catalyzes the reversible reaction between 7-ketolithocholic acid (7K-LCA) and ursodeoxycholic acid (UDCA). However, its much lower forward reaction activity led to the unsatisfactory UDCA production. Here, by autodocking 7K-LCA and UDCA into the structure of Hyphomicrobium sp.

Bio-inspired Catalyst-Modified Photocathode for Bias-Free Photoelectrochemical NADH Regeneration.

Cofactors such as nicotinamide adenine dinucleotide (NADH) and its phosphorylated form (NADPH) play a crucial role in natural enzyme-catalyzed reactions for the synthesis of chemicals. However, the stoichiometric supply of NADH for artificial synthetic processes is uneconomical. Here, inspired by the process of cofactor NADPH regeneration in photosystem I (PSI), catalyst-modified photocathodes are constructed on the surface of polythiophene-based semiconductors (PTTH) via self-assembly for photoelectrochemical catalytic NADH regeneration.
