Patent ID: 7972789

Claim:
A method for precipitating at least one compound of formula: wherein, in said compound: dotted lines Z 1 and Z 2 represent the atoms necessary to complete the formula chosen from one ring, two fused rings, and three fused rings, each said ring comprising 3 to 6 carbon atoms wherein at least one of said rings has attached at least one aromatic amine group (—NH 2 ), at least one aromatic hydroxyl group (—OH), at least one aromatic phosphate group (—PO 4 ), or a mixture thereof; k, m, and n are independently 0 or 1; X and Y are independently chosen from oxygen, sulfur, selenium, —C(CH 3 ) 2 —, and —CH═CH—; and A 1 , A 2 , and R 1-13 are independently chosen from -D and —(B) i -(D) j , wherein D is chosen from: i.) a neutral group that reduces water solubility; ii.) a polar group that increases water solubility; iii.) an electron donating group; iv.) an electron withdrawing group; v.) a functional group; vi.) a group that is a substrate for an enzyme, said group being chosen from a phosphate group, a hydroxyl group and an amino group; and vii.) a mixture thereof; and B is chosen from: branched alkyl chains of 1 to 20 carbon atoms: straight alkyl chains of 1 to 20 carbon atoms; monoethers containing 2 to 20 carbon atoms; polyethers containing 2 to 20 carbon atoms; and polymethine chains containing 1 to 6 carbon atoms; wherein i and j are independently integers from 0 to 6; said method comprising the steps: (a) providing said at least one compound; (b) providing at least one enzyme; (c) contacting said at least one compound with said at least one enzyme; and (d) optionally providing at least one co-factor; wherein said at least one compound forms a precipitate.
