Protein

Proteasome subunit beta type-2

Gene

PBD1

Organism
Oryza sativa subsp. japonica (Rice)
Status
Reviewed - Annotation score: 3 out of 5- Experimental evidence at transcript leveli

Functioni

The proteasome is a multicatalytic proteinase complex which is characterized by its ability to cleave peptides with Arg, Phe, Tyr, Leu, and Glu adjacent to the leaving group at neutral or slightly basic pH. The proteasome has an ATP-dependent proteolytic activity (By similarity).By similarity

Catalytic activityi

Cleavage of peptide bonds with very broad specificity.

Interactioni

Subunit structurei

The 26S proteasome consists of a 20S proteasome core and two 19S regulatory subunits. The 20S proteasome core is composed of 28 subunits that are arranged in four stacked rings, resulting in a barrel-shaped structure. The two end rings are each formed by seven alpha subunits, and the two central rings are each formed by seven beta subunits. The catalytic chamber with the active sites is on the inside of the barrel (By similarity).By similarity
