Since the 1863 discovery of a new green hemoglobin derivative called “sulfhemoglobin”, the nature of its characteristic 618 nm absorption band and formation mechanism has been the subject of several hypotheses. Many ...

Lucina pectinata’s ctenidia contains three hemeproteins: the hydrogen sulfide reactive hemoglobin I (HbI) and the oxygen transporting hemoglobins II and III (HbII and HbIII) that remain unaffected by the presence of H2S. ...

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 ...

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 ...

The clam Lucina pectinata Hemoglobin I (HbI) is a monomeric protein with a prosthetic group, known as heme group, in which the iron atom can either be in the ferrous (Fe(II)) or the ferric (Fe(III)) oxidation state. This ...

The extraordinary affinity of recombinant hemoglobin I from Lucina pectinata (rHbI) for hydrogen sulfide (H2S) allow to postulate it as substrate for the preparation of the hydrogen sulfide sensors. The modification of a ...
