Hevea brasiliensis seeds: A novel sustainable feedstock for ethanol production

open access: yesVietnam Journal of Chemistry, EarlyView.
Abstract The rubber tree (Hevea brasiliensis) is cultivated on a large scale mainly for the extraction of latex in Brazil and Southeast Asia, also generating large quantities of seeds. These seeds currently do not have large‐scale applications and may thus be considered as a residue.

SARS‐CoV‐2 nucleocapsid protein variants have differential RNA chaperone activity

open access: yesThe FEBS Journal, EarlyView.
The SARS‐CoV‐2 nucleocapsid (N) protein facilitates RNA annealing through its RBD–IDR2–CTD region, identifying it as a functional RNA chaperone. The Omicron BA.5 variant shows reduced chaperone activity compared to the Wuhan wild‐type protein. Although phosphorylation has no effect on wild‐type N, phosphomimetic modification of BA.5 N restores its RNA ...

A Hanks‐type bacterial kinase, PknS, directly phosphorylates the alternative sigma factor EcfK to promote resistance to protist predation

open access: yesThe FEBS Journal, EarlyView.
The Xanthomonas citri Hanks‐type kinase PknS autophosphorylates and directly phosphorylates the alternative sigma factor EcfK at five residues. Besides the conserved residue T51 in the σ2 domain, phosphorylation of a residue in the linker between σ2 and σ4 is critical for EcfK activation by promoting its interaction with a positively charged pocket in ...

Comparative evaluation of noncanonical amino acids as site‐specific NMR probes for the complex of E. coli SSB with single‐stranded DNA without isotope labelling

open access: yesThe FEBS Journal, EarlyView.
Genetic encoding of noncanonical amino acids (ncAA) enables their site‐specific installation in proteins. This work compares the nuclear magnetic resonance (NMR) performance of different ncAAs in a large protein−DNA complex (~ 100 kDa) without isotope labelling. The ncAAs deliver readily detectable NMR signals in the complex between E.

PLP Homeostasis Protein Is Required for Efficient Maturation of Aromatic Amino Acid Aminotransferase in Salmonella enterica

open access: yesMolecular Microbiology, EarlyView.
Cellular pool of aromatic amino acid aminotransferase proteins represented as holo‐ or apo‐ enzymes, reflecting presence or absence of associated PLP. Status of PLPHP is implicated in determining the ratio of holo‐ and apo‐TyrB. ABSTRACT Pyridoxal 5′‐phosphate (PLP) is an essential cofactor required for metabolic functions including amino acid ...

In Salmonella Typhimurium, YiiD Modulates cAMP Levels in Lag Phase During Growth on Succinate

open access: yesMolecular Microbiology, EarlyView.
The YiiD enzyme, found by others to perform a redundant role in fatty acid biosynthesis, is found to be unexpectedly required for the early increase in cAMP in lag phase during growth on succinate. This intriguing finding suggests a mechanistic link may exist between fatty acid biosynthesis and catabolite repression. ABSTRACT In Salmonella Typhimurium (

Bioconversion of carotenoids into high‐value crocins using a marine sponge carotenoid cleavage dioxygenase

open access: yesNew Phytologist, EarlyView.
Summary Carotenoids and apocarotenoids are widespread specialized metabolites, yet animals, including sponges, lack the ability to synthesize carotenoids de novo and must obtain them from dietary or microbial sources. The roles of carotenoid cleavage dioxygenases (CCDs) in marine animals remain largely unexplored. A CCD from the marine sponge Suberites

Cyclophilin A‐mediated cis/trans isomerization modulates RIN4 to control intracellular rhizobial infection in legumes

open access: yesNew Phytologist, EarlyView.
Summary In most legume‐rhizobium symbioses, rhizobial colonization occurs through host‐derived intracellular infection threads, which enable rhizobial recruitment while presumably modulating the host immune system to prevent rejection. To investigate post‐translational regulation of immune responses during rhizobial infection, we focused on Cyclophilin
