these collagen polypeptides , as well as those encoded by the previously sequenced c. elegans collagen genes col-1 and col-2 , share a common organization into five domains : an amino-terminal leader , a short ( 30-33 aa ) ( gly-x-y ) n domain , a non ( gly-x-y ) spacer , a long ( 127-132 aa ) ( gly-x-y ) n domain , and a short carboxyl-terminal domain .
