Evidences for balancing selection from PAH-BglII and PAH-EcoRI polymorphisms in Isfahan population

open access: yesتاکسونومی و بیوسیستماتیک, 2010
Two polymorphic markers including BglII and EcoRI, were identified at intron 1 and intron 5 of PAH gene. In order to test whether these polymorphisms are behaving as neutral alleles or are being subjected to selective pressures in Isfahan population, 110

Phycocyanobilin biosynthesis in Galdieria sulphuraria requires isomerization of phycoerythrobilin synthesized by bilin reductases

open access: yesThe FEBS Journal, EarlyView.
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

open access: yesThe FEBS Journal, EarlyView.
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 ...

Identification and nucleotide sequences of mxaA, mxaC, mxaK, mxaL, and mxaD genes from Methylobacterium extorquens AM1 [PDF]

open access: yes, 1995
The DNA sequence for a 4.4-kb HindIII-XhoI Methylobacterium extorquens AM1 DNA fragment that is known to contain three genes (mxaAKL) involved in incorporation of calcium into methanol dehydrogenase (I. W. Richardson and C. Anthony, Biochem. J.

The FsrA‐Mediated Iron‐Sparing Response Regulates the Biosynthesis of the Epipeptide EPE in Bacillus subtilis

open access: yesMolecular Microbiology, EarlyView.
Under iron‐limited conditions, FsrA base‐pairs with the intergenic region between epeX and epeE, enhancing epeE translation and triggering EPE production. Toxin‐mediated cell lysis releases nutrients, including iron, which can be taken up by surviving cells.

Late Stage Mannan Metabolism in Cellvibrio japonicus Requires the Combined Action of a Mannosyl‐Glucose Phosphorylase and a Mannobiose Epimerase

open access: yesMolecular Microbiology, EarlyView.
Model for the non‐PTS utilization of manno‐oligosaccharides by Cellvibrio japonicus. The Mgp130A and EpiA enzymes are essential for the utilization of mannose residues. ABSTRACT Manno‐oligosaccharides and their metabolism play important roles in gut health, pharmaceutical development, and renewable chemical production.

Erythrocyte Membrane Protein 3 (EMAP3) Is Exposed on the Surface of the Plasmodium berghei Infected Red Blood Cell

open access: yesMolecular Microbiology, EarlyView.
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.

Designing and cloning a MaSp1-based synthetic gene in binary vector for transient expression in cotton fiber

open access: yesیافته‌های نوین در علوم زیستی, 2016
Cotton (Gossypium hirsutum L.) is an important crop in the world and increasing its fiber quality is very cr-ucial for textile industries. Spider silk is the strongest and most elastic fiber ever known in the nature.
