Exploring the Roles of Heme Type and Histidine -Tyrosine Cross -Link in Heme-Copper Oxidases Using a Myoglobin Model
Novel oxygen reactivity is observed in our model protein (CuBMb) which reproduces the most essential components of HCO active site. In order to improve this artificial model to inhibit its side reaction with oxygen and channel it toward oxidase reactivity, more features were introduced into the …

The Heme -Copper Oxidoreductase Superfamily: Genomics and Structural Analyses
… that the C-type oxygen reductases contain a histidine-tyrosine crosslinked cofactor analogous to that found in the A- and B-families However in the C-family the tyrosine participating in the crosslink is found to originate within a different transmembrane helix than in the A- and B-families. …

Characterization of the insecticidal crystal protein from Bacillus thuringiensis.
… destruction of the side-chains of tryptophan, histidine, tyrosine and methionine. Destruction of amino acid side-chains is not the primary cause of the photo-inactivation of the protein crystal. The finding that all the disulfide linkages in the protein crystal are interchain and symmetrical …

Elucidating the Roles of Conserved Active Site Amino Acids in the Escherichia coli Cytochrome c Nitrite Reductase
… dominated by a conserved catalytic triad of histidine, tyrosine and arginine residues. The role of the catalytic triad of Escherichia coli NrfA has been explored by generating NrfA variants. Three NrfA variants were studied in which a single active site residue was substituted: arginine to …

Automated data acquisition and analysis for high-resolution Fourier transform mass spectrometry of proteins and peptides
"This thesis details the progress made in automating the data acquisition and data processing of MS and MS/MS data from Fourier transform ion cyclotron resonance mass spectrometers. These instruments have made great strides in the past few years, moving from labor-intensive, largely manual systems …
