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. ...
New crystallographic structures of Oxy-HbII-III and CN-HbII-III forms from Lucina pectinata
The clam Lucina pectinata is found in the sulfide-rich southwest coastal sediments of La Parguera, Puerto Rico in the Caribbean Sea. This bivalve mollusk has developed a chemoautotrophic symbiotic relation with the bacteria ...
Crystal structures of hemeproteins: Sulf and H2S myoglobin derivatives and Lucina pectinata Oxy (HbII-HbIII) and Oxy (HbIII-HbIII) systems
As a gasotransmitter, hydrogen sulfide (H2S) biochemistry in humans is of pivotal importance. One relevant reaction of H2S in our bodies is its interaction with hemeproteins. The threshold of its beneficial/harmful effects ...
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 ...
