In Vivo Biosynthesis and Direct Incorporation of Non‐Canonical Amino Acids into Proteins

open access: yesChemBioChem, Accepted Article.
Autonomous cells are engineered biological systems capable of biosynthesising and directly incorporating non‐canonical amino acids (ncAAs) into proteins. These systems have the potential to extend the applicability of the genetic code to enable large‐scale fermentative production of proteins carrying ncAAs.

Identification of a l‐Threonine‐Utilizing Hydrazine Synthetase for Thrazarine Biosynthesis in Streptomyces coerulescens MH802‐fF5

open access: yesChemBioChem, EarlyView.
A putative thrazarine biosynthetic gene cluster is discovered in the genome sequence of Streptomyces coerulescens MH802‐fF5. In vivo and in vitro analyses of ThzN, a hydrazine synthetase with cupin and methionyl‐tRNA synthetase‐like domains encoded in the cluster, showed that it synthesizes a key intermediate of thrazarine by catalyzing condensation ...

Dominant‐Negative Effects of p53 R337 Variants in Li–Fraumeni Syndrome: Impact on Tetramer Formation and Transcriptional Activity

open access: yesChemBioChem, EarlyView.
Hetero‐tetramer dysfunction: Li–Fraumeni syndrome (LFS) is a hereditary cancer predisposition caused by mutations in the TP53 gene encoding the tumor suppressor p53. It is shown that p53 variants R337C and R337H, found in LFS, impair wild‐type (WT) p53 function by forming heterotetramers with reduced transcriptional activity.

The Rarity in the Rarity: Presentation of Three Cases of Cutaneous Carcinosarcoma with Clinical and Histopathological Insights

open access: yesDermatopathology
A cutaneous carcinosarcoma (cCS) is a rare and aggressive skin cancer characterized by both carcinomatous (epithelial) and sarcomatous (mesenchymal) components, making it a biphasic tumor.

Identification of Pyrrolizilactone Biosynthetic Gene Cluster with Unique Short‐Chain Dehydrogenase Gene for 3‐Methylproline Formation

open access: yesChemistryEurope, EarlyView.
A standalone enzyme, derived from the reductase domain of a polyketide synthase‐nonribosomal peptide synthetase hybrid enzyme, is identified as a pyrroline carboxylate reductase. This enzyme is involved in the biosynthesis of 3‐methylproline, an amino acid building block of a unique tricyclic pyrrolizidinone structure of a fungal metabolite ...
