Methylation of the N6 position selected internal adenines (m(6)A) in mRNAs and noncoding RNAs is widespread eukaryotes, YTH domain a collection proteins recognizes this modification. We report crystal structure splicing factor YT521-B homology (YTH) Zygosaccharomyces rouxii MRB1 complex with heptaribonucleotide an m(6)A residue center. The modification recognized by aromatic cage, being sandwiched between Trp Tyr methyl group pointed toward another residue. Mutations residues RNA binding...

Significance The small nucleotide cyclic di-3′,5′-adenosine monophosphate (c-di-AMP) recently emerged as a ubiquitous signaling molecule among bacteria, with essential roles in both bacterial physiology and host–pathogen interactions. Bacterial mutants abnormal c-di-AMP levels exhibit growth virulence defects, reflecting the importance of regulating synthesis degradation for normal signal transduction adaptation to changing environments. Previously documented phosphodiesterases hydrolyze via...

Technological advances in rare DNA mutations detection have revolutionized the diagnosis and monitoring of tumors, but they are still limited by lack supersensitive high-coverage procedures for identifying low-abundance mutations. Here, we describe a single-tube, multiplex PCR-based system, A-Star, that involves hyperthermophilic Argonaute from Pyrococcus furiosus (PfAgo) highly efficient beneficial its compatibility with polymerase. This novel technique uses specific guide design strategy...

The facultative intracellular pathogen Listeria monocytogenes, like many related Firmicutes, uses the nucleotide second messenger cyclic di-AMP (c-di-AMP) to adapt changes in nutrient availability, osmotic stress, and presence of cell wall-acting antibiotics. In rich medium, c-di-AMP is essential; however, mutations cbpB, gene encoding binding protein B, suppress essentiality. this study, we identified that reason for cbpB-dependent essentiality through induction stringent response by RelA....

Aromatic polyketides are renowned for their wide-ranging pharmaceutical activities. Their structural diversity is mainly produced via modification of limited types basic frameworks. In this study, we characterized the biosynthesis a unique aromatic framework, phenyldimethylanthrone (PDA) found in (+)/(−)-anthrabenzoxocinones (ABXs) and fasamycin (FAS). Its employs methyltransferase (Abx (+) M/Abx (−) M/FasT) an unusual TcmI-like aromatase/cyclase (ARO/CYC, Abx D/Abx D/FasL) as well...

MDC1 is a key mediator of the DNA-damage response in mammals with several phosphorylation-dependent protein interaction domains. The function its N-terminal forkhead-associated (FHA) domain remains elusive. Here, we show structural, biochemical and cellular data that FHA mediates dimerization to DNA damage. Crystal structures reveal face-to-face dimer pseudo-dyad symmetry. We found recognizes phosphothreonine 4 (pT4) at N-terminus determined crystal structure complex pT4 peptide. Biochemical...

Aromatic polyketides are an important class of natural products with various bioactivities, and their structural diversity arises from modifications to aromatic frameworks. In this study, we identify a stereoselective aromatase/cyclase (ARO/CYC) FasU, which is responsible for forming the axial chiral biphenyl framework in fasamycin. FasU catalyzes sequential decarboxylation cyclization/aromatization strict S-stereospecificity on previously unidentified biosynthetic intermediate. Through...

SUMMARY COP1 is a critical repressor of plant photomorphogenesis in darkness. However, plays distinct roles the photoreceptor UVR8 pathway Arabidopsis thaliana . interacts with ultraviolet B (UV‐B)‐activated monomers and promotes their retention accumulation nucleus. Moreover, has function UV‐B signaling, which involves binding its WD40 domain to HY5 via conserved Val‐Pro (VP) motifs these proteins. UV‐B‐activated both core VP motif, leading displacement from stabilization. it remains...

Abstract Pseudomonas species and other aerobic bacteria have a biotin-independent malonate decarboxylase that is crucial for their utilization of as the sole carbon energy source. The holoenzyme contains four subunits, having an acyl-carrier protein (MdcC subunit) with distinct prosthetic group, well (MdcD–MdcE) transferase (MdcA) catalytic activities. Here we report crystal structure hetero-tetramer, biochemical functional studies based on structural information. We observe molecule in...
