ABSTRACT:
Electrophoretically homogeneous human Antineoplastic Urinary Protein (ANUP) contains a blocked N-terminal amino acid that has been identified as pyroglutamic acid. Removal of the pyroglutamy residue by the use of pyroglutamyl aminopeptidose results in the formation of the deblocked protein which is also an antineoplastic molecule. The amino acid sequence of the deblocked ANUP 16 KD monomer showed the following sequence:
Cycle No.
