The amino acid sequence of a peptide isolated from a CNBr digest of the erythrocyte Ca2+ ATPase has been determined. It contains a highly conserved phosphorylation site sequence common to all aspartyl-phosphate forming ion motive ATPases which have been sequenced so far.

L-valine holds wide-ranging applications in medicine, food, feed, and various industrial sectors. Escherichia coli, a pivotal strain in industrial L-valine production, features a concise fermentation period and a well-defined genetic background. This study focuses on mismatch repair genes (mutH, mutL, mutS, and recG) and genes associated with mutagenesis (dinB, rpoS, rpoD, and recA), employing a high-glucose adaptive culture in conjunction with metabolic modifications to systematically screen for superior phenotypes.

Multiple sclerosis (MS) is a neurological disease causing myelin and axon damage through inflammatory and autoimmune processes. Despite affecting millions worldwide, understanding its genetic pathways remains limited. The choroid plexus (ChP) has been studied in neurodegenerative processes and diseases like MS due to its dysregulation, yet its role in MS pathophysiology remains unclear.

Soil salinity poses a significant environmental challenge for the growth and development of blueberries. However, the specific mechanisms by which blueberries respond to salt stress are still not fully understood. Here, we employed a comprehensive approach integrating physiological, metabolomic, and transcriptomic analyses to identify key metabolic pathways in blueberries under salt stress.

A new strategy has been developed to successfully produce the active component danshensu ex vivo. For this purpose, phenylalanine dehydrogenase from Bacillus sphaericus was combined with the novel hydroxyphenylpyruvate reductase from Mentha x piperita, thereby providing an in situ cofactor regeneration throughout the conversion process. The purified enzymes were co-immobilized and subsequently employed in batch biotransformation, resulting in 60% conversion of 10 mM L-dopa within 24 h, with a catalytic amount of NAD as cofactor.
