Signaling by H2S is proposed to occur via persulfidation, a posttranslational modification of
cysteine residues (RSH) to persulfides (RSSH). Persulfidation provides a framework for …

Historically, hydrogen sulfide (H2S) has been regarded as a poisonous gas, with a wide
spectrum of toxic effects. However, like· NO and CO, H2S is now referred to as a signaling …

Hemoglobin I (HbI) from the clam Lucina pectinata is an intriguing hemeprotein that binds
and transports H2S to sulfide-oxidizing chemoautotrophic bacteria to maintain a symbiotic …

The extracellular hemoglobin of Glossoscolex paulistus (HbGp) is constituted of subunits
containing heme groups, monomers and trimers, and nonheme structures, called linkers …

All plants contain an unusual class of hemoglobins that display bis-histidyl coordination yet
are able to bind exogenous ligands such as oxygen. Structurally homologous …

The effects of two ionic surfactants on the oligomeric structure of the giant extracellular
hemoglobin of Glossoscolex paulistus (HbGp) in the oxy-form have been studied through …

A red blood cell (RBC) from human exhibited direct electron transfer (DET) activity on a bare
indium tin oxide (ITO) electrode. A formal potential of− 0.152 V vs. a silver–silver chloride …

Lucina pectinata ctenidia harbor three heme proteins: sulfide-reactive hemoglobin I (HbI Lp)
and the oxygen transporting hemoglobins II and III (HbII Lp and HbIII Lp) that remain …

(1) Introduction: Lucina pectinata is a clam found in sulfide-rich mud environments that has
three hemoglobins believed to be responsible for the transport of hydrogen sulfide (HbILp) …

Plasmodium falciparum, the most deadly human malaria parasite, poses a major threat to
human health worldwide, with over 500 million clinical cases and between one and two …
