Ion Transit Pathways and Gating in ClC Chloride Channels [PDF]
arXiv, 2004 ClC chloride channels possess a homodimeric structure in which each monomer contains an independent chloride ion pathway. ClC channel gating is regulated by chloride ion concentration, pH, and voltage. Based on structural and physiological evidence, it has been proposed that a glutamate residue on the extracellular end of the selectivity filter acts as

Critical appraisal on mitochondrial dysfunction in Alzheimer’s disease
AGING MEDICINE, Volume 5, Issue 4, Page 272-280, December 2022., 2022 Amyloid plaques deposit on neurons in case of Alzheimer's Disease. Mitochondria play a vital role in pathogenesis of Alzheimer's Disease. Mitochondrial dysfunction can lead to formation of mPTP, alteration of complexes 1,3 and 4, deficits in bioenergetics with impaired mitochondrial biogenesis. Abstract It is widely recognized that Alzheimer's disease (

Human glutaminyl cyclase and bacterial zinc aminopeptidase share a common fold and active site
BMC Biology, 2004 Background Glutaminyl cyclase (QC) forms the pyroglutamyl residue at the amino terminus of numerous secretory peptides and proteins. We previously proposed the mammalian QC has some features in common with zinc aminopeptidases.

Three phases in the evolution of the standard genetic code: how translation could get started [PDF]
arXiv, 2007 A primordial genetic code is proposed, having only four codons assigned, GGC meaning glycine, GAC meaning aspartate/glutamate, GCC meaning alanine-like and GUC meaning valine-like. Pathways of ambiguity reduction enlarged the codon repertoire with CUC meaning leucine, AUC meaning isoleucine, ACC meaning threonine-like and GAG meaning glutamate ...
