Tropoelastin is encoded by a single human gene that spans 36 exons and is oxidized in vivo by mammalian lysyl oxidase at the epsilon amino group of available lysines to give the adipic semialdehyde , which then facilitates covalent cross link formation in an enzyme free process involving tropoelastin association . ^^^ We demonstrate here that this process is effectively modeled by a two protein component system using purified lysyl oxidase from the yeast Pichia pastoris to facilitate the oxidation and subsequent cross linking of recombinant human tropoelastin . ^^^ |
