1.5.5.2 ATP - 739932 1.5.5.2 coenzyme Q1 coenzyme Q1 is electron acceptor for PRODH/POX, which passes electrons directly to coenzyme Q1 (CoQ1) RODH/POX binds directly to CoQ1 without the formation of a tertiary complex. The transfer of electrons from proline to CoQ1 by PRODH/POX is dependent on downstream electron transfer from CoQ1 to Complexes III and IV 741588 1.5.5.2 cytochrome c - 743635 1.5.5.2 FAD - 392556, 392560, 392570, 696361, 724345, 724389, 739932, 742487 1.5.5.2 FAD 1.96 mol per mol of enzyme complex 658668 1.5.5.2 FAD determination of key amino acids involved in FAD-binding site and catalysis reaction, involving residues Ser165, Lys195 and Ala252 742641 1.5.5.2 FAD enzyme-bound, dependent on. Addition of excess FAD hardly improves the enzyme activity, confirming that the enzyme is fully saturated with FAD 742162 1.5.5.2 FAD FAD may be released by 1 M KBr, apoprotein has no proline dehydrogenase activity but may be restored by external addition of FAD 392571 1.5.5.2 FAD flavin cofactor, 1.2fold stimulated by exogenous FAD 722591 1.5.5.2 FAD non-covalent binding 741732
