Tartrate resistant acid phosphatase is a glycosylated monomeric metalloenzyme expressed in mammals. It has a molecular weight of approximately 35kDa, a basic isoelectric point (7.6-9.5) , and optimal activity in acidic conditions. TRAP is synthesized as latent proenzyme and activated by proteolytic cleavage and reduction. It is differentiated by other mammalian acid phosphatases by its resistance to inhibition by tartrate, molecular weights and characteristic purple colour.
