Hydrogen bonding to the cysteine ligand of superoxide reductase: acid--base control of the reaction intermediates [PDF]
Journal of biological inorganic chemistry : JBIC : a publication
of the Society of Biological Inorganic Chemistry, 2013, 18, pp.815 - 830, 2015 Superoxide reductase SOR is a non-heme iron metalloenzyme that detoxifies superoxide radical in microorganisms. Its active site consists of an unusual non-heme Fe2+ center in a [His4 Cys1] square pyramidal pentacoordination, with the axial cysteine ligand proposed to be an essential feature in catalysis.

Leucine and isoleucine requirements of the kitten [PDF]
British Journal of Nutrition, 1984 1. In separate experiments the isoleucine and leucine requirements of the kitten were determined on the basis of growth and nitrogen retention. The dietary concentrations of isoleucine tested were (g/kg diet) 1.4, 2.2, 3.0, 3.8, 4.6 and 9.0 with adequate (12.0 g/kg diet) leucine.

A search for mid-IR bands of amino acids in the Perseus Molecular Cloud [PDF]
arXiv, 2023 Amino acids are building-blocks of proteins, basic constituents of all organisms and essential to life on Earth. They are present in carbonaceous chondrite meteorites and comets, but their origin is still unknown. We present Spitzer spectroscopic observations in the star-forming region IC 348 of the Perseus Molecular Cloud showing the possible ...
