In the search for biocatalysts for degradation of nonnatural polymers, reactive immunization with haptens 7 and 11 was used to prepare catalytic antibodies capable of cleaving short oligomeric esters, as well as the insoluble polyester 25. These antibodies were found to be highly specific and efficient esterases for oligomers. Triester 24 was preferentially hydrolyzed by an endo-cleavage pathway, however
在寻找用于降解非天然聚合物的生物催化剂时,用半抗原7和11进行反应性免疫制备了能够裂解短的低聚酯以及不溶性聚酯25的催化抗体。发现这些抗体是针对寡聚物的高度特异性和有效的酯酶。三酯24优先通过内切途径水解,但是,使用较高分子量的聚合物25则无法观察到位点特异性。由于物理限制,抗体对不溶性聚合物25的催化效率受到限制。
