Seven regions can be recognized on gels and a maximum of bands is found with alpha naphtyl acetate as substrate. The capacity of ester hydrolysis is seen to decline gradually with successively longer chain carbon substrates except for region II (maximum activity with alpha naphtyl caprylate). These results seem to be consistent with Choudbury's suggestion that non specific esterases all belong to one enzyme system whose structure is built on a subunit structure and exhibit overlapping specificities though sharing of common subunits. A genetic analysis shows that five independant autosomal loci control the variations at polymorphic regions (regions I, II, III and IV) in the three species.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Caractérisation biochimique et polymorphisme des estérases dans le complexe d'espèces affines <i>Jaera albifrons</i> Leach (crustacé, isopodes) = Characterization and polymorphism of the esterases in the complex of <i>Jaera albifrons</i> Leach (Crustacea, Isopoda)","OrigTitleLangCode":"fr","OrigTitleLangCodeExtended":"fre","OrigTitleLangID":22,"DateLastModified":{"date":"2024-12-10 01:33:17.368041","timezone_type":1,"timezone":"+01:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":1981,"MonPub":null,"DateUpdate":"2016-02-29","DateCreate":"2004-06-10","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":null,"VABBcode":null,"OpenAcc":1},"refs":null,"anarec":{"AnaID":62857,"PubliDate":1981,"Pagination":"185-192","XtraPublOfAnaID":null,"ISBN":null,"Volume":"22","Issue":"2","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":42348,"SerRR":"Cahiers de Biologie Marine.
