Green Fluorescent Protein Variants as Ratiometric Dual Emission pH Sensors.1.Structural Characterization and Preliminary Application
Animals Cricetulus Cell Line Threonine Luminescent Proteins Green Fluorescent Proteins Microscopy, Confocal Crystallography, X-Ray Transfection Amino Acid Substitution
2016/5/24
Novel dual emission, pH-sensitive variants of the green fluorescent protein (GFP) have been constructed and are suitable for ratiometric emission measurements in vivo. This new class of GFPs, termed d...
19F NMR of Trifluoroacetyl-Labeled Cysteine Mutants of Myoglobin:Structural Probes of Nitric Oxide Bound to the H93G Cavity Mutant
19F NMR Trifluoroacetyl Cysteine Mutants Myoglobin Nitric Oxide H93G Cavity Mutant
2016/5/23
Nitric oxide (NO) binds to the myoglobin (Mb) cavity mutant, H93G, forming either a 5- or 6-coordinate Fe--NO heme complex. The H93G mutation replaces the proximal histidine of Mb with glycine, allowi...
Structural changes between signaling states of bacterial chemoreceptors probed by solid -state NMR and hydrogen exchange
Structure of membrane protein lipid environment membrane signals bacteria chemical sensors membrane domains solid-state nuclear magnetic resonance (NMR)
2014/12/11
The limitations of structural studies of membrane proteins imposed by the lipid environment has made it difficult to determine the molecular mechanism of transmembrane signaling. For the bacterial che...
Structural and functional characterization of the unique N-terminus of Cse4p, A histone H3 -like protein at the S. cerevisiae centromere
Budding yeast the yeast protein protein fission yeast etc
2014/12/11
The budding yeast (S. cerevisiae) centromere component, Cse4p is an evolutionarily conserved histone H3-like protein, with homologues identified in fission yeast, worm, fly and human. All histone H3-l...
Functional tests of structural models for abortive cycling in T7 RNA polymerase
Pure sciences Biological sciences Abortive cycling RNA polymerase Transcription
2014/12/10
Transcription initiates when the enzyme binds to the promoter region and melts open an initial transcribing bubble that extends from position -4 to +4. The initiation phase continues until the enzyme ...
