Recombinant human LOX protein

LOX is an extracellular copper enzyme that initiates the crosslinking of collagens and elastin. The enzyme catalyzes oxidative deamination of the epsilon-amino group in certain lysine and hydroxylysine residues of collagens and lysine residues of elastin. In addition to crosslinking extracellular matrix proteins, the encoded protein may have a role in tumor suppression. Defects in this gene are a cause of autosomal recessive cutis laxa type I (CL type I) . Two transcript variants encoding different isoforms have been found for this gene. Recombinant human LOX protein, fused to His-tag at N-terminus, was expressed in E. coli.
