Protein Synthesis Flashcards
What two ways is translation completed
Translation on free ribosomes:cystolic proteins, peripheral membrane proteins targeted to nucleus mitchondria perioxisomes chloroplasts
Translation completed by ribosomes attached to ER
What three proteins are synthesized in rough er
Secreted proteins
Integral membrane proteins
Soluble proteins associated inside endomembrane system
What is a signal sequence
What ribosomes are targeted to the ER membrane by
Directs synthesis to ER
What is cotranslational transport
Signal sequence located at animo (N) terminus directs synthesis to ER protein moves through channel to ER
What is a signal recognition protein
After translation of signal sequence SRP binds to signal sequence and translation stops
What is translation
Ribosomes sythesise polypeptides from mRNA
