Recombinant enzymes are catalytically active proteins produced through expression of engineered DNA that encodes the enzyme in a biological host. The coding sequence is incorporated into an expression construct whose regulatory elements support transcription and translation in the selected organism. The encoded protein may retain a naturally occurring sequence or contain deliberately introduced sequence changes [1]. Formation of an active recombinant enzyme can require folding, assembly of subunits, incorporation of cofactors, proteolytic processing, or other post-translational modifications [2][3]. These requirements interact with the biochemical capabilities of the expression host [2]. The enzyme may accumulate within cells or enter a secretion pathway, and its mature molecular form depends on both the encoded sequence and host-mediated processing [4][4]. The term identifies the recombinant origin of the enzyme and does not specify a single catalytic reaction, protein family, or expression organism [1][2].
