Spectroscopic properties of rubber oxygenase RoxA from Xanthomonas sp., a new type of dihaem dioxygenase.


Natural rubber [poly-(cis-1,4-isoprene)] is cleaved to 12-oxo-4,8-dimethyltrideca-4,8-diene-1-al (ODTD) by rubber oxygenase A (RoxA) isolated from Xanthomonas sp. RoxA has two c-type haem centres that show two distinct alpha-bands at 549 and 553 nm in the dithionite-reduced state. A well-resolved midpoint potential (E(0)') of -65 mV was determined for one… (More)
