I-Cellulose yeyona polymer ininzi enokuphinda ihlaziywe emhlabeni kunye nenxalenye enkulu yodonga lweseli yesityalo.Kwizityalo ze-vascular, i-cellulose synthesis is catalyzed by a big, plasma membrane-localized cellulose synthase complex (CSC), ebonwa njenge-hexameric rosette structure.Ii-isoform ezintathu ezizodwa ze-cellulose synthase (CESA) ziyafuneka kwindibano yeCSC kunye nomsebenzi.Nangona kunjalo, ukucaciswa nokuba ngaba inani okanye i-stoichiometry yee-CESAs ngaphakathi kwe-CSC kuhleli kunzima.Kwesi sifundo, sibonisa i-1: 1: 1 stoichiometry phakathi kwe-Arabidopsis thaliana yesibini isozymes eludongeni lweseli: CESA4, CESA7, kunye ne-CESA8.Lo mlinganiselo wamiselwa kusetyenziswa indlela elula kodwa ebukekayo yokuthintela ukugonywa komzimba ngokomlinganiselo kusetyenziswa izilwa-buhlungu ze-isoform-specific kunye (35) nemigangatho yeprotheyini ebhalwe ngu-S kwi-CESA nganye.Ukongezelela, i-equimolar stoichiometry ebonwayo ifunyenwe ilungiswe ecaleni kwe-axis yesiqu, emele i-gradient yophuhliso.Iziphumo zethu zihambelana nohlalutyo lwamva nje lwe-spectroscopic olubhekiselele kwi-18-chain cellulose microfibril.Xa sidibene, siphakamisa ukuba i-CSC yenziwe ngehexamer ye-catalytically active CESA trimers, kunye ne-CESA nganye ngeemali ezilinganayo.Oku kufunyanisiweyo kukuhamba phambili okubalulekileyo ekuqondeni ukuba ii-CESAs zihlangana njani ukuze zenze iikhompleksi zodidi oluphezulu, eyona nto ibalulekileyo yokumisela i-cellulose microfibril kunye neempawu zodonga lweseli.
