Histidines 138 and 143 are Copper Binding Ligands in , Phenylalanine Hydroxylasehe active site. and more recently by X-ray absorption spectroscopy of the copper containing enzyme.. We have used a combination of site directed mutagenesis and pulsed EPR spectroscopy to probe the copper binding site of CV PAH and identify the Cu(II) ligands.

Estimating Particle Number and Sizein nature xanthopterin (.) and leucopterin (.). In 1933 a third component, isoxanthopterin (.)., was isolated, but his constitution remained also unknown until Robert Purrmann was able to elucidate the structures of all three pigments., which turned out to be derivatives of the pyrazine pyrimidine (.) ringsystem termed by Wieland...
