For α-antithrombin, the additional glycosylation at Asn-135 is not thought to interfere with initial heparin binding, but rather to inhibit any resulting conformational changes.
Para a α-antitrombina, a glicosilación adicional na Asn-135 non se cre que interfira coa unión de heparina inicial, senón que máis ben inhibe calquera cambio conformacional resultante.
