PMID: 1917929
The dimeric hemoglobin isolated from Scapharca inaequivalvis, HbI, is notable for its highly cooperative oxygen binding and for the unusual proximity of its heme groups. We now report that the...

264(19):11302-6.
PMID: 2738066
Spectrofluorometric techniques were used to quantify NADPH-hemoglobin interactions based on the quenching of NADPH fluorescence upon binding to hemoglobin. Fluorometric titrations were carried out with hemoglobin in varied states and...

. 1987 Jan;
20(6):755-8.
PMID: 3455253
The affinity constants for the binding of NADPH to human hemoglobin A were directly determined by fluorescence analysis since nucleotide fluorescence is quenched on binding to the protein. The binding...
