Enzymes 1 Flashcards
Kinase group
Transfer phosphate groups from one molecule to another using a nucleotide phosphate as donor
Aminotransferase
Transfer amino acids using pyridoxine phosphate
Examples of co enzymes
- Tetrahydrofolate
- Pyridoxal phosphate
- Co enzyme A
Competitive Inhibition
Vmax is unchanged, but km increases.
Examples of competitive inhibitors
( ASRC)
- Atorvastatin = 3H3MG CoA Reductase = Hypolipidaemia.
Competitive Inhibitor
- Sildenafil = cGMP PDE5 = Erectile dysfunction.
Competitive Inhibitor
Ritonavir = HIV Protease = Antiretoviral
Competitive Inhibitor
Captopril = ACE = Antihypertensive.
Non competitive Inhibitors = Vmax is reduced, Km us constant.
(ANDT)
Acetazolamide = carbonic anhydrase = Glaucoma, Weak diuretic.
Non competitive Inhibitors
- Nevirapine = HIV reverse transcriptase = Antiretroviral.
Non competitive Inhibitors
- Doxycycline = Collagenase = Arthritis.
Non competitive Inhibitors
- Tacrine = AChe = Alzheimer’s disease
Uncompetitive Inhibitors, Vmax decreases, Km decreases [ LFC]
- Lithium = Impase = Mania
Uncompetitive Inhibitors
- Finasteride = 5 alpha reductase = BPH
Uncompetitive Inhibitors
- Camptothecin = Topoisomerase = Anticancer.
