Effect of the E11 amino acid on the ligand binding in Hemoglobin I from Lucina pectinata
Hemoglobin I (HbI) from Lucina pectinata (clam) is a protein that binds and transports H2S to the bacteria in the clam. HbI is one of the few known hemoglobins that carries H2S, toxic gas, in its active site, which contains ...
Hemoglobin I from Lucina pectinata: A model for hydrogen sulfide reactivity within hemeproteins
The hemoglobin I (HbI) from the clam Lucina pectinata is an intriguing hemeprotein that binds and transports H2S to chemoautotrophic bacteria to maintain a symbiotic relationship and to protect the mollusk from H2S toxicity. ...
The role of position E11 in the stabilization of the HbI-SH2 complex from L. pectinata
The bivalve mollusk, Lucina pectinata, contains three hemoglobins: hemoglobin I (HbI) which is a H2S reactive protein, hemoglobin II (HbII) and hemoglobin III (HbIII) which deliver O2 to the organism. HbI is a monomeric ...
Expression and purification of Lucina pectinata recombinant hemoglobin II and the effect of the oxygen affinity on the heme pocket
Lucina pectinata is a bivalve mollusk that inhabits sulfide rich sediments along, the west coast of Puerto Rico. This clam contains three hemoglobins that deliver and transport oxygen (HbII and III) and hydrogen sulfide ...
