The gene of NAD`-dependent formate dehydrogenase (FDH) from Mycobacterium vaccae N10 was cloned into Escherichia coli by hybridization with digoxigenin-labeled DNA probes, which were prepared by amplification of the chromosomal DNA from the bacterium by the polymerase chain reaction with degenerate primers. The primers were designed on the basis of the most conserved parts of known sequences of...

Biobutanol is a sustainable green biofuel that can substitute for gasoline. Carbon flux has been redistributed in Clostridium tyrobutyricum via metabolic cell engineering to produce biobutanol. However, the lack of reducing power hampered the further improvement of butanol production. The objective of this study was to improve butanol production by rebalancing redox. Firstly, a metabolically-en...

We link the FDR treatment of ultraviolet (UV) divergences to dimensional regularization up to two loops in QCD. This allows us to derive the one-loop and two-loop coupling constant and quark mass shifts necessary to translate infrared finite quantities computed in FDR to the MS renormalization scheme. As a by-product of our analysis, we solve a problem analogous to the historical difficulties o...

Focal dermal hypoplasia (Goltz syndrome) is a rare syndrome comprising developmental anomalies of tissues and organs of mesoectodermal origin. As a result, there are abnormalities of the eyes, skin, oral structures, musculoskeletal system and central nervous system. This article describes the case of a four-year-old female with focal dermal hypoplasia (FDH) who displayed many of the oral featur...

The in situ regeneration of reduced nicotinamide cofactors (NAD(P)H) is necessary for practical synthesis of many important chemicals. Here, we report the engineering of a highly stable and active mutant phosphite dehydrogenase (12x-A176R PTDH) from Pseudomonas stutzeri and evaluation of its potential as an effective NADPH regeneration system in an enzyme membrane reactor. Two practically impor...

Human serum albumin (HSA) is the major protein component of blood plasma and serves as a transporter for thyroxine and other hydrophobic compounds such as fatty acids and bilirubin. We report here a structural characterization of HSA-thyroxine interactions. Using crystallographic analyses we have identified four binding sites for thyroxine on HSA distributed in subdomains IIA, IIIA, and IIIB. M...

The calculation of loop amplitudes with parity violation or spin effects within dimensional regularization needs a consistent definition of γ5. Also loop calculations in supersymmetric theories need a consistent definition of γ5. In this paper we develop a new formalism, which allows us to define consistent regularization schemes. We use Grothendieck’s K-functor to construct finite-dimensional ...

CO2 emissions are the primary reason for global warming; hence, biological and chemical technologies converting into useful compounds being actively studied. Biological methods using enzymes can convert under mild conditions. Formate dehydrogenase (FDH) is a representative conversion enzyme. Its function was revealed after isolation from bacteria, yeast, plants. In this study, we evaluated pote...
