Cellulose ke polymer e nchafalitsoeng ka ho fetisisa Lefatšeng le karolo e kholo ea lerako la lisele tsa semela.Limeleng tsa methapo ea mali, motsoako oa cellulose o hlahisoa ke motsoako o moholo oa plasma-localized cellulose synthase complex (CSC), o bonoang e le sebopeho sa rosette ea hexameric.Ho hlokahala li-isoform tse tharo tse ikhethang tsa cellulose synthase (CESA) bakeng sa kopano le ts'ebetso ea CSC.Leha ho le joalo, tlhaloso ea palo kapa stoichiometry ea CESAs ka har'a CSC e ntse e le thata.Thutong ena, re bonts'a 1:1:1 stoichiometry lipakeng tsa li-isozyme tse tharo tsa "Arabidopsis thaliana" tsa lerako la bobeli: CESA4, CESA7, le CESA8.Karo-karolelano ena e ile ea etsoa qeto ea ho sebelisa mokhoa o bonolo empa o le bokhabane oa quantitative immunoblotting ho sebelisoa li-antibodies tse khethehileng tsa isoform le (35) S-leibole litekanyetso tsa protheine bakeng sa CESA ka 'ngoe.Ho feta moo, stoichiometry ea equimolar e hlokometsoeng e fumanoe e tsitsitse haufi le axis ea kutu, e emelang sekhahla sa nts'etsopele.Liphetho tsa rona li tlatselletsa litlhahlobo tsa morao-rao tsa spectroscopic tse supang ho 18-chain cellulose microfibril.Ha re kopantsoe hammoho, re sisinya hore CSC e entsoe ka hexamer ea li-trimers tsa CESA tse sebetsang hantle, 'me CESA ka 'ngoe e lekana ka bongata.Sephetho sena ke tsoelo-pele ea bohlokoa ea ho utloisisa hore na li-CESA li hokahana joang ho theha li-complexes tsa maemo a holimo, e leng sesupo sa mantlha sa cellulose microfibril le thepa ea lebota la lisele.
