View solution

Q. Once the proteins are translocated within the organelles, protease cleavage takes place to remove the signal sequences and generate mature proteins.

View solution

Q. The signal sequences have a _________ consensus but contain some specific features. They all have a ______ core region preceded by one or more positively charged residues.

View solution

Q. The signal sequences are typically _______ residues long, rich in _____ charged residues such as arginines as well as hydroxyl residues such as serines and threonines, but devoid of ______ charged residues.

Q. Chloroplast localization signals are also located in the __________ terminus and are about 25 to 100 residues in length, containing very few _______ charged residues but many hydroxylated residues such as serine.

View solution

Q. Chloroplast localization signals consist of two adjacent signal peptides, one for targeting the proteins to the stromaportion of the chloroplast before being cleaved and the other for targeting the remaining portion of the proteins to the thylakoids.
