A common structural motif in thiamin pyrophosphate-binding enzymes [PDF]
, 1989 The amino acid sequences of a wide range of enzymes that utilize thiamin pyrophosphate (TPP) as cofactor have been compared. A common sequence motif approximately 30 residues in length was detected, beginning with the highly conserved sequence -GDG- and ...

Advanced Science, Volume 12, Issue 22, June 12, 2025.We developed a citramalate‐derived pathway for 2‐methylbutyric acid production in E. coli mono‐culture and consortia. The optimized consortium, using 2‐keto‐3‐methylvalerate as a node, achieved 1817.03 ± 103.73 mg L−1 2‐methylbutyric acid, a 28‐fold increase from the initial strain, with a yield of 0.091 g/g glucose.

Biotechnology and Bioengineering, Volume 122, Issue 6, Page 1561-1573, June 2025.ABSTRACT Escherichia coli accumulates acetate as a byproduct in fast growth aerobic conditions when using glucose as carbon source. This phenomenon, known as overflow metabolism, has negative impacts on cell growth and protein expression, also causes carbon loss during biosynthesis in most microbial production scenarios. In this study, we regarded the “

Stimulation of Enzyme Reaction Rates by Crystalline Substrate Irradiation: Dependence on Identity of Irradiated Substance [PDF]
arXiv, 2013 The study reported here concerns a phenomenon, discovered and extensively investigated by Sorin Comorosan, wherein enzyme initial reaction rates are enhanced as a consequence of incorporation of solutions derived from previously irradiated crystalline material into the reaction medium.

Characterization of Nuclear Magnetism at Ultralow and Zero Field using SQUIDs [PDF]
IEEE Transactions on Applied Superconductivity, 2025Nuclear magnetism underpins areas such as medicine in magnetic resonance imaging (MRI). Hyperpolarization of nuclei enhances the quantity and quality of information that can be determined from these techniques by increasing their signal to noise ratios by orders of magnitude. However, some of these hyperpolarization techniques rely on the use of low to
