Microbial synthesis of m-tyrosine via whole-cell biocatalysis.

Meta-tyrosine (m-tyrosine), a nonproteinogenic amino acid, has shown significant potential for applications as an herbicide in agriculture and for various medical uses. However, the natural abundance of m-tyrosine is very low, limiting its widespread use. In this study, we successfully achieved microbial production of m-tyrosine by establishing the in vivo enzyme activity of phenylalanine 3-hydroxylase (PacX from Streptomyces coeruleoribudus) in E.

Background: The two-stage surgical technique of associated liver partition and portal vein ligation for staged hepatectomy (ALPPS) enables extensive liver resection and promotes future liver remnant regeneration (FLR), in part by inhibiting the Hippo signalling pathway. Its main effector, Yes-associated protein (YAP), has low intrinsic transcriptional activity and requires the transcription enhanced associated domain factor (TEAD) family members as cofactors for target gene transcription. We evaluated the intracellular localization and expression of TEAD1-4, hypothesized to regulate the activity of YAP and, consequently, liver regeneration.

Cyclic dipeptides are produced by organisms across all domains of life, with many exhibiting anticancer and antimicrobial properties. Oxidations are often key to their biological activities, particularly C-C bond oxidation catalysed by tailoring enzymes including cyclodipeptide oxidases. These flavin-dependent enzymes are underexplored due to their intricate three-dimensional arrangement involving multiple copies of two distinct small subunits, and mechanistic details underlying substrate selection and catalysis are lacking.

Background: The wide variability in clinical responses to anti-tumor immunotherapy drives the search for personalized strategies. One of the promising approaches is drug screening using patient-derived models composed of tumor and immune cells. In this regard, the selection of an appropriate in vitro model and the choice of cellular response assay are critical for reliable predictions.

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.
