Cards

Term
Streptomycin
Definition
Causes misreading of the genetic code in prokaryotes. Interferes with initiation.
Term
Tetracycline
Definition
Inhibits binding of aminoacyl-tRNA to A-site
Term
Choramphenicol
Definition
Inhibits peptidyl transferase activity on ribosomes
Term
Erythromycin
Definition
Binds to the 50S subunit and inhibits translocation
Term
Puromycin
Definition
Resembles aminoacyl-tRNA and binds to A-site which causes premature release of polypeptide chain
(prokaryotes and eukaryotes)
Term
Cycloheximide
Definition
Inhibits peptidyl transferase activity of the 60S ribosome (Eukaryotes)
Term
Diphtheria toxin
Definition
Inhibits eEF-2 and prevents translocation
Term
Ricin
Definition
Inactivates 60S subunit of ribosome
Term
Thiamin
Definition
Vitamin B1, converted to thiamine pyrophosphate TPP, with pyruvate dehydrogenase it cleaves a C-C bond in pyruvate to create acetaldehyde.
Term
Riboflavin
Definition
Vitamin B2, coenzyme for FAD and FMN
Term
Niacin
Definition
Important for coenzymes NAD and NADP. Required in large amounts
Term
Pantothenic Acid
Definition
Forms Coenzyme A which transports acetyl groups from one substrate to another
Term
Lipoic Acid
Definition
Term
Pyridoxine
Definition
Term
Biotin
Definition
Acts as a cofactor for enzymes that add carboxyl groups to substrates.
Term
Vitamin B12
Definition
Most complex vitamin, complexed with Cobalt. It is required for methyl transfer
Term
Folic Acid
Definition
Important target for antibiotics and anticancer. Important for single carbon unit reactions and formation of nucleotides.
Term
Ascorbic Acid
Definition
Vitamin C. Protects cells from reactive oxygen species as an antioxidant.
Term
Vitamin K
Definition
fat soluble vitamin. Inportant in the prothrombin pathway. Anticlotting drugs work by blocking the enzyme that reduces Vitamin K.
Term
Methotrexate
Definition
Anticancer drug inhibits human DHFR and since tetrahydrofolate is required for the production of nucleic acid bases-cancer cell production is blocked.
Term
Trimethoprim
Definition
Trimethoprim works on bacterial DHFR and is an antibacterial agent
