Abstract
La presente invención incluye métodos para preparar polisacáridos anticoagulantes usando varias enzimas sulfotransferasa diseñadas no naturales que están diseñadas para reaccionar con compuestos de sulfato de arilo en lugar del sustrato natural, 3'-fosfoadenosina 5'-fosfosulfato, para facilitar la transferencia del grupo sulfo al aceptadores de grupo sulfo de polisacáridos. Los compuestos de sulfato de arilo adecuados incluyen, pero no se limitan a, sulfato de p-nitrofenilo o sulfato de 4-nitrocatecol. Los polisacáridos anticoagulantes producidos mediante los métodos de la presente invención comprenden residuos de glucosamina N-, 3-O-, 6-O-sulfatados y residuos de ácido hexurónico 2-O sulfatados, tienen una actividad anticoagulante comparable en comparación con los polisacáridos anticoagulantes disponibles comercialmente y pueden ser usados para formar polisacáridos anticoagulantes truncados que tengan un peso molecular reducido.
