Rapid nerve conduction in myelinated nerves requires the clustering of voltage-gated sodium channels at nodes of Ranvier. The Neurofascin (Nfasc) gene has a unique role in node formation because it encodes glial and neuronal isoforms of neurofascin (Nfasc155 and Nfasc186...

Journal of Alzheimer's disease : JAD, 48(1), 115-121 (2015-09-25)
Alzheimer's disease (AD) is known to exhibit well characterized pathologies including the extracellular accumulation of amyloid plaques, intra-axonal presence of neurofibrillary tangles, and glial hypertrophy. Nevertheless, the nature of myelin pathology in AD has not been well studied. Recent studies...

We report an analysis of the reaction mechanism of ornithine 4,5-aminomutase, an adenosylcobalamin (AdoCbl)- and pyridoxal L-phosphate (PLP)-dependent enzyme that catalyzes the 1,2-rearrangement of the terminal amino group of D-ornithine to generate (2R,4S)-2,4-diaminopentanoic acid. We show by stopped-flow absorbance studies...
