This 73 kDa protein is an extracellular enzyme that catalyzes oxidative C-C cleavage of poly(cis-1,4-isoprene) to a major product, 12-oxo-4,8-dimethyltrideca-4,8-diene-1-al (ODTD; C15 tri-isoprenoid), with specific activity measured as 0.3 mol min-1 per mg. Found not only in Xanthomonas sp. but also in other Gram-negative clearing zone formers, RoxA is structurally related to cytochrome c peroxidases and its function is associated to two covalently bound heme groups. Although recently characterized by Birke et al (1), the exact enzymatic mechanism of rubber degradation by RoxA has not yet been elucidated.

Rubber oxygenase A - rubber degrading enzyme

Part BBa_K1819003 corresponds to the coding sequence of rubber oxygenase A (Rox A) from Xanthomonas sp. strain 35Y (Gene bank accession code: AGT20506.1.) This 73 kDa protein is an extracellular enzyme that catalyzes oxidative C-C cleavage of poly(cis-1,4-isoprene) to a major product, 12-oxo-4,8-dimethyltrideca-4,8-diene-1-al (ODTD; C15 tri-isoprenoid), with specific activity measured as 0.3 mol min-1 per mg. Found not only in Xanthomonas sp. but also in other Gram-negative clearing zone formers, RoxA is structurally related to cytochrome c peroxidases and its function is associated to two covalently bound heme groups. Although recently characterized by Birke et al (1), the exact enzymatic mechanism of rubber degradation by RoxA has not yet been elucidated. This protein was codon optimized by
