Catalyzes the oxidative C-C cleavage of poly(cis-1,4-isoprene) in synthetic as well as in natural rubber by the addition of oxygen (O2) to the double bonds, leading to a mixture of oligonucleotide-isoprenoids with terminal keto and aldehyde groups (endo-type cleavage) (PubMed:25819959, PubMed:24907333). The cleavage products are of different lengths, ranging from C20 (four isoprene units) to higher oligo-isoprenoids (PubMed:24907333). Is not able to cleave low-molecular-weight substrate analogs with isoprenoid structure such as squalene (1,4-trans-isoprenoid), carotenoids, or alpha-tocopherol (PubMed:24907333).<ref>PMID:15638519</ref> <ref>PMID:18606806</ref> <ref>PMID:22950008</ref> <ref>PMID:24907333</ref> <ref>PMID:25819959</ref> | |||

== Publication Abstract from PubMed == | |||
Latex clearing proteins (Lcps) are rubber oxygenases that catalyse the extracellular cleavage of poly (cis-1,4-isoprene) by Gram-positive rubber degrading bacteria. Lcp of Streptomyces sp. K30 (LcpK30) is a b-type cytochrome and acts as an endo-type dioxygenase producing C20 and higher oligo-isoprenoids that differ in the number of isoprene units but have the same terminal functions, CHO-CH2- and -CH2-COCH3. Our analysis of the LcpK30 structure revealed a 3/3 globin fold with additional domains at the N- and C-termini and similarities to globin-coupled sensor proteins. The haem group of LcpK30 is ligated to the polypeptide by a proximal histidine (His198) and by a lysine residue (Lys167) as the distal axial ligand. The comparison of LcpK30 structures in a closed and in an open state as well as spectroscopic and biochemical analysis of wild type and LcpK30 muteins provided insights into the action of the enzyme during catalysis. | |||
