Cards

Term
streptomyocin
Definition
stops initiation in prokaryotes, binds to the 30S subunit and distorts its structure, interfering with the initiation of protein synthesis
Term
tetracyclines
Definition
interact with 30S ribosomal subunits, blocking access of the aminoacyl-tRNA to mRNA-ribosome complex
Term
peptidyltransferase
Definition
an activity of the rRNA of the 50S ribosomal subunit, transfers the amino (or peptide chain ) from the P-site onto the amino acid at the A-site and catalyzes peptide bond formation
Term
puromyocin
Definition
causes inhibition of furthur elongation of the peptide chain in both prokaryotes and eukaryotes
Term
chloramphenicol
Definition
inhibits prokaryotic peptidyltransferase, high levels may also inhibit mitochondrial protein synthesis
Term
clindamycin and erythromycin
Definition
bind irreversibly to a site on the 50S subunit of the bacterial ribosome thus inhibiting translocation
Term
diphtheria toxin
Definition
inactivates eukaryotic elongation factor (eEF2) preventing translocation
Term
actinomyosin D
Definition
binds to minor DNA groove and prevents DNA replication
Term
Quinolones, ciprofloxin, noroblocin
Definition
inihibits DNA gyrase in bacteria and prevents DNA replication
Term
Etoposide
Definition
inhibits Type II Human Gyrase and prevents DNA replication
Term
AZT-araA
Definition
altered sugar with no 3 prime OH group; prevents elongation and proofreading
Term
Rifampin
Definition
binds Beta subunits is prokaryotes and prevents transcription
