Characterization of the pattern of development of key compounds contributing to aroma quality of chicken meat and their metabolic markers

Animal Research and One Health, EarlyView.
The graphical abstract shows the principal results of this study. Eight major aroma‐contributing compounds (nonanal, octanal, dimethyl tetrasulfide, hexanal, 1‐octen‐3‐ol, (E)‐2‐nonenal, heptanal, and (E,E)‐2,4‐decadienal) were identified by electronic nose and GC‐O‐MS analysis, and their content increased with age.

Investigation of a broad‐spectrum micronutrient formulation as a possible precipitant of pharmacokinetic micronutrient–drug interactions

British Journal of Clinical Pharmacology, EarlyView.
Aims Daily broad‐spectrum micronutrients are being used by the general public and formulations are receiving research interest in mental health settings. Despite concerns about combining medicines and broad‐spectrum micronutrients in mental health care, there have not been any formal evaluations of potential interactions.

Sigma Factors as Potential Targets to Enhance Recombinant Protein Expression

Biotechnology and Bioengineering, EarlyView.
ABSTRACT The transcriptional factors control the expression of many genes and represent an important layer of complexity in cell factories. However, the effect of individual sigma factor deletions from a biomanufacturing perspective has not been addressed. In this contribution, growth, green fluorescence protein (GFP) expression, and oxygen consumption

High‐sensitivity real‐time monitoring of pH and respiration activity unveils metabolic dynamics in shake flask cultures

Biotechnology Progress, EarlyView.
Abstract Erlenmeyer shake flasks are widely used during the first steps of bioprocess development. Despite their broad application in academia and industry, shake flasks usually lack standardized and user‐friendly online monitoring techniques. In this work, the pH and Respiratory Activity MOnitoring System (pH‐RAMOS) for the non‐invasive online ...

Online monitored characterization of Phocaeicola vulgatus for organic acid production using anaerobic microtiter plate cultivations

Biotechnology Progress, EarlyView.
Abstract Phocaeicola vulgatus (formerly Bacteroides vulgatus), an anaerobic gut bacterium, produces several organic acids. Research on P. vulgatus is still in its infancy. However, a detailed understanding of P. vulgatus growth and metabolism is essential for its assessment as an organic acid producer.

Thiamin pyrophosphokinase is required for thiamin cofactor activation in Arabidopsis

Plant Molecular Biology, 2007
Thiamin pyrophosphate (TPP) is an essential enzyme cofactor required for the viability of all organisms. Whether derived from exogenous sources or through de novo synthesis, thiamin must be pyrophosphorylated for cofactor activation. The enzyme thiamin pyrophosphokinase (TPK) catalyzes the conversion of free thiamin to TPP in plants and other ...

Apparent Reversal of Allosteric Response in Mycobacterium tuberculosis MenD Reveals Links to Half‐of‐Sites Reactivity

ChemBioChem, EarlyView.
A combination of computational, biochemical and structural studies on allostery mutants of Mtb‐MenD, a menaquinone (vitamin K2) biosynthesis enzyme from a human pathogen, yields insight into the interrelationship between allosteric and half‐of‐sites reactivity mechanisms.

Enzymatic Upgrading of Biomass‐Derived Aldoses to Rare Deoxy Ketoses Catalyzed by Transketolase Variants

ChemSusChem, EarlyView.
A sustainable, convenient, scalable, one‐step method for the two‐carbon chain elongation of cheap, biomass‐derived pentoses (l‐arabinose, and 2‐deoxy‐d‐ribose) and a hexose (l‐rhamnose) was developed to produce Cn+2 deoxy ketoses (C‐7 and C‐8) using transketolase, an enzyme catalyzing the irreversible transfer of a ketol group from an α‐ketoacid to an ...
