Identity and function of an essential nitrogen ligand of the nitrogenase cofactor biosynthesis protein NifB. [PDF]
, 2020 NifB is a radical S-adenosyl-L-methionine (SAM) enzyme that is essential for nitrogenase cofactor assembly. Previously, a nitrogen ligand was shown to be involved in coupling a pair of [Fe4S4] clusters (designated K1 and K2) concomitant with carbide ...

Two-dimensional protein crystallization via metal-ion coordination by naturally occurring surface histidines [PDF]
, 1996 A powerful and potentially general approach to the targeting and crystallization of proteins on lipid interfaces through coordination of surface histidine residues to lipid-chelated divalent metal ions is presented.

Muscle carnosine metabolism and β-alanine supplementation in relation to exercise and training [PDF]
, 2010 Carnosine is a dipeptide with a high concentration in mammalian skeletal muscle. It is synthesized by carnosine synthase from the amino acids L-histidine and beta-alanine, of which the latter is the rate-limiting precursor, and degraded by carnosinase ...

Proton transfer in histidine-tryptophan heterodimers embedded in helium droplets
, 2015 We used cold helium droplets as nano-scale reactors to form and ionize, by electron bombardment and charge transfer, aromatic amino acid heterodimers of histidine with tryptophan, methyl-tryptophan, and indole. The molecular interaction occurring through

Modulating Linker Composition of Haptens Resulted in Improved Immunoassay for Histamine. [PDF]
, 2019 Histamine (HA) is an important food contaminant generated during food fermentation or spoilage. However, an immunoassay for direct (derivatization free) determination of HA has rarely been reported due to its small size to induce the desired antibodies ...
