In this study, we confirm that PlqH is the hydroxylase operating in plastoquinone biosynthesis in photosynthetic cyanobacteria (Cyanobacteriia). Our phylogenetic analyses demonstrate that cyanobacterial PlqH homologues originated from hydroxylases involved in ubiquinone biosynthesis in bacteria. Plastoquinone production in Escherichia coli was achieved

Molecular basis of antibiotic sensing by the TetR family regulator CecR – a structural perspective
Escherichia coli CecR, a member of the TetR family regulators, senses selected antibiotics and activates the expression of a putative drug efflux pump. Although present in many pathogenic Enterobacteriales strains, CecR remains poorly characterized. We present the first CecR crystal structure, which reveals a unique tunnel‐like ligand‐binding cavity ...

Long-term cultures of murine fetal liver retain very early B lymphoid phenotype. [PDF]
Long-term cultures of murine fetal liver have been successfully established using a modification of our in vitro bone marrow culture system (14, 15).

The biosynthesis of bilins, tetrapyrroles essential for light harvesting and sensing, is performed by specific enzymes (FDBRs). In Galdieria sulphuraria, both phycobiliprotein types bind phycocyanobilin, despite lacking the canonical synthesizing gene PCYA. Instead, PEBA and PEBB are encoded, producing phycoerythrobilin, proposed to be later isomerized

Regulation of PHOX2B gene expression by the long non‐coding natural antisense RNA PHOX2B‐AS1
PHOX2B is a transcription factor essential for autonomic nervous system development. We identify and characterize PHOX2B‐AS1, a human long non‐coding antisense transcript at the PHOX2B locus, along with its murine counterpart. Our findings reveal bidirectional transcription and reciprocal regulation: PHOX2B activates PHOX2B‐AS1, whereas PHOX2B‐AS1 ...

Erythrocyte membrane protein 3 (EMAP3) is a novel Plasmodium berghei protein that is trafficked to the outer membrane surface of the infected red blood cell (iRBC). EMAP3 is not critical for parasite growth or sequestration but offers a new scaffold for displaying Plasmodium falciparum proteins on iRBCs.

Abstract Infection is a known cause of abdominal aortic aneurysm (AAA), and matrix metalloproteases‐2 (MMP‐2) secreted by vascular smooth muscle cells (SMCs) plays a key role in the structural disruption of the middle layer of the arteries during AAA progression.

ABSTRACT Catharanthus roseus contains nearly 200 bioactive monoterpenoid indole alkaloids (MIAs) that are effective in treating cancer and other diseases. Ethylene plays a significant role in enhancing MIA biosynthesis, and we have found that it greatly induces the accumulation of anhydrovinblastine.
