Abstract
Provided herein are phenylalanine ammonia-lyase (PAL) variants produced by prokaryotes, wherein such prokaryotic PAL variant has a greater phenylalanine-converting activity and/or a reduced immunogenicity as compared to a wild-type PAL. Further provided are compositions of prokaryotic PAL and biologically active fragments, mutants, variants or analogs thereof, as well as methods for the production, purification, formulation, and use of such compositions for industrial and therapeutic purposes, e.g., treating hyperphenylalaninemia, including phenylketonuria, and other disorders, including cancer.
