产品内容
本酶催化的反应为Cleavage Of Cis-1,4-Polyisoprene Polymers Into A Mixture Of Compounds, Including A C20 Compound ((4Z,8Z,12Z,16Z,20Z,24Z)-4,8,12,16,20,24-Hexamethyl-28-Oxononacosa-4,8,12,16,20,24-Hexaenal), A C25 Compound ((4Z,8Z,12Z,16Z,20Z)-4,8,12,16,20-Pentamethyl-24-Oxopentacosa-4,8,12,16,20-Pentaenal), A C30 Compound ((4Z,8Z,12Z,16Z)-4,8,12,16-Tetramethyl-20-Oxohenicosa-4,8,12,16-Tetraenal), And Larger Isoprenologes Such As C35, C40, C45, And Higher Analogues.系统名称为Cis-1,4-Polyisoprene:oxygen Dioxygenase (Endo-Cleaving)，该酶催化天然和合成橡胶中双键的断裂，产生末端带酮基和醛基的 C20、C25、C30 及更高级寡异戊二烯的混合物。已知两种不相关的细菌酶具有此活性——来自链霉菌（Streptomyces sp.）K30 的该酶（Lcp）含有一个 b 型细胞色素，而来自黄单胞菌（Xanthomonas sp.）35Y 的该酶（RoxB）含有两个 c 型细胞色素。两种酶都在随机位置进攻底物，且不能将 C35 或更小的产物切割成更短的片段。
