Enzyme reactions

• Enzyme class 1: Chains A, B: E.C.2.5.1.58 - Protein farnesyltransferase.
• Reaction: Farnesyl diphosphate + protein-cysteine = S-farnesyl protein + diphosphate

Farnesyl diphosphate (Bound ligand (Het Group name = FPP) corresponds exactly) + protein-cysteine = S-farnesyl protein + diphosphate

• Cofactor: Magnesium; Zinc
• Enzyme class 2: Chain A: E.C.2.5.1.59 - Protein geranylgeranyltransferase type I.
• Reaction: Geranylgeranyl diphosphate + protein-cysteine = S-geranylgeranyl- protein + diphosphate

Geranylgeranyl diphosphate (Bound ligand (Het Group name = FPP) matches with 82.00% similarity) + protein-cysteine = S-geranylgeranyl- protein + diphosphate

• Cofactor: Zinc

Note, where more than one E.C. class is given (as above), each may correspond to a different protein domain or, in the case of polyprotein precursors, to a different mature protein.

ABSTRACT

1,3,5,5-Tetrasubstituted 2,4-imidazolinedione (hydantoin) derivatives were evaluated as Ftase inhibitors. Potent Ftase inhibitors without thiol or peptide were obtained in three steps.
