It is a large extracellular protein, with a blue colour, which has a typical hexameric structure (Markl & Decker, 1992) and a large potential for functional plasticity (Truchot & Lallier, 1992). Although in vivo data would be necessary to infer true physiological adaptations to the vent environment, it is tempting to speculate from the in vitro characteristics of haemocyanin presented in this paper. The quaternary structure seems to be essentially correlated with the taxonomy of the studied species: the two shrimps (<i>C. chacei</i> and <i>R. exoculata</i>) exhibit the usual predominance of hexameric haemocyanin, whereas the crabs (<i>B. thermydron</i> and <i>C. praedator</i>) possess a larger proportion of dodecamers. The subunit composition apparently shows a similar pattern to other crustaceans (Markl & Decker, 1992) but it should be more accurately determined using modern techniques such as mass spectrometry. The functional properties of oxygen binding, however, appear to be related to the respective habitat of each species. <i>R. exoculata</i> and <i>C. praedator</i>, which are believed to live in warmer waters, close to the vent chimneys, exhibit some common functional properties like a moderate Hc-O<sub>2</sub>  affinity due to one or several unknown factors which decrease this affinity. This unique potential to lower affinity could eventually prove beneficial in the large physico-chemical gradient in which they live. Conversely, <i>C. chacei</i> and <i>B. thermydron</i> which live in cooler waters, among <i>Bathymodiolus</i> and <i>Riftia</i> respectively, exhibit an higher Hc-O<sub>2</sub> affinity due to a more pronounced lactate effect. This tentative scheme needs to be substantiated with detailed information on the microenvironment of each species, which in turn would allow in vivo experiments to be conducted in appropriate conditions.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Structure and function of hydrothermal vent crustacean haemocyanin: an update","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-04-21 01:31:38.512858","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":1998,"MonPub":null,"DateUpdate":"2021-02-16","DateCreate":"2004-10-01","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000078751400024","VABBcode":null,"OpenAcc":1,"DOI":"10.21411/CBM.A.5426C7A7"},"refs":null,"anarec":{"AnaID":66640,"PubliDate":1998,"Pagination":"313-316","XtraPublOfAnaID":null,"ISBN":null,"Volume":"39","Issue":"3-4","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":42348,"SerRR":"Cahiers de Biologie Marine.
