The crystal structure of the Borrelia burgdorferi nicotinamidase BBE22 resolves a long-standing annotation error. [PDF]

open access: yesFEBS Open Bio
The crystal structure of Borrelia burgdorferi nicotinamidase (PncA/BBE22) reveals the correct full‐length protein initiated from a non‐canonical AUU start codon. The structure validates previous biochemical findings and resolves a long‐standing annotation error, demonstrating that the truncated database sequence is structurally incompatible with the ...

Structure-Function Studies of Nicotinic Acetylcholine Receptors Using Unnatural Amino Acids [PDF]

open access: yes, 2012
This dissertation primarily describes structure-function studies of the nicotinic acetylcholine receptors (nAChRs). These studies use a combination of unnatural amino acid mutagenesis and electrophysiology to determine the specific molecular interactions

Differing time dependencies of object recognition memory impairments produced by nicotinic and muscarinic cholinergic antagonism in perirhinal cortex [PDF]

open access: yes, 2011
The roles of muscarinic and nicotinic cholinergic receptors in perirhinal cortex in object recognition memory were compared. Rats' discrimination of a novel object preference test (NOP) test was measured after either systemic or local infusion into the ...

In Vivo Incorporation of Multiple Unnatural Amino Acids [PDF]

open access: yes, 2009
Unnatural amino acid (UAA) incorporation is an invaluable technique that is seeing increased use. THG73 is an amber suppressor tRNA used to incorporate > 100 residues at the UAG, amber stop codon, in Xenopus oocytes.

Scientific Opinion on the safety and efficacy of niacin (nicotinic acid and nicotinamide) as a feed additive for all animal species based on a dossier submitted by Lonza Benelux BV [PDF]

open access: yesEFSA Journal, 2012
<p>The term ‘niacin’ is used as a generic description of nicotinic acid and nicotinamide with pyridine as the basic structure. Nicotinic acid and nicotinamide function mainly as precursors of the co-enzymes NAD and NADP.

Effects of solvent and structure on the reactivity of 6-substituted nicotinic acids with diazodiphenylmethane in aprotic solvents [PDF]

open access: yesJournal of the Serbian Chemical Society, 2009
The rate constants for the reactions of diazodiphenylmethane (DDM) with 6-substituted nicotinic acids in aprotic solvents at 30 °C were determined. The obtained second order rate constants in aprotic solvents, together with literature data for benzoic ...
