Basic Information of Protein

Overview of Protein Modification Sites with Functional and Structural Information
UniProt ID	PSA2B_ARATH
UniProt AC	Q8L4A7
Protein Name	Proteasome subunit alpha type-2-B
Gene Name	PAB2
Organism	Arabidopsis thaliana (Mouse-ear cress).
Sequence Length	235
Subcellular Localization	Cytoplasm. Nucleus.
Protein Description	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..
