Saccharomyces cerevisiae alcohol dehydrogenase (SCAD) was effectively immobilized on hybrid alginate-chitosan beads which are hardened with glutaraldehyde. Immobilization conditions and characterization of the immobilized enzyme were investigated. Orthogonal test design and intuitive analysis method were employed to evaluate the effects
Thiamin diphosphate (ThDP) is the biologically active form of vitamin B(1), and ThDP-dependent enzymes are found in all forms of life. The catalytic mechanism of this family requires the formation of a common intermediate, the 2α-carbanion-enamine, regardless of whether the

Associations between occupational styrene exposure and impairment of hearing function were investigated, guided by three questions: are there hearing losses concerning high frequency and standard audiometric test? Are there dose-response relationships and measurable thresholds of effects? Are there signs of

Mechanistic details of the Mg(2+) ion-activated enantioselective reduction of methyl benzoylformate have been investigated at a B3LYP/6-31G* theory level, using peptide NADH models 1 rigidified with a beta-lactam ring. Computation of the reaction pathway revealed important structural differences between the

Ethylbenzene is an important industrial chemical that has recently been classified as a possible human carcinogen (International Agency of Research on Cancer class 2B), but the available data do not support the genotoxic mechanism of ethylbenzene-induced tumors in kidney. We
