Contributing Reviewer — Biochemistry
[PhD/MD credentials pending]
This entry is a structural placeholder for a PhD-level biochemist or molecular biologist whose primary expertise is the enzymology and metabolic regulation of NAD+. On assignment, the contributor filling this slot will hold primary review responsibility for mechanism-focused content across the site: pages under /mechanisms, precursor metabolism entries under /precursors, and any article section that makes a claim about enzyme kinetics, cofactor chemistry, or intracellular NAD+ flux. Typical review scope includes: the NAD+ salvage pathway (NAMPT, NMNAT isoforms), de novo synthesis from tryptophan via the kynurenine pathway, Preiss-Handler pathway entry from niacin, sirtuin (SIRT1-7) deacylation chemistry and substrate specificity, PARP1/2 activity in DNA damage response, CD38 as the dominant NADase in aging tissue, SARM1 in axonal degeneration, and the compartmentalization of NAD+ pools across cytosol, mitochondria, and nucleus. The contributor is also responsible for vetting claims about precursor bioavailability at the molecular level — specifically whether a given precursor crosses membranes intact, is dephosphorylated extracellularly, or requires a specific transporter. Credentials, institutional affiliation, ORCID, and publication history will be added when a named individual is assigned. Until then, articles requiring biochemistry-domain review default to the editorial-team collective byline.
