最近发现的染料脱色过氧化物酶(DYPs)在一大群血红素过氧化物酶中形成了一个遥远的谱系。除其他外,DYPS可催化复杂的蒽醌染料的降解。它们的结构主要是螺旋的,具有显著的β-Sheet折叠,这是其他血红素过氧化物酶中没有的一个基序。最近,密集的研究表明DyP超家族在微生物中广泛存在,并且在功能方面比之前想象的要多得多。本文综述了DyP类过氧化物酶及其已知的生物学、化学和结构特征。 3D结构 来自黑木耳的单体AauDyP(A)、来自圆氏希瓦氏菌的TyrA的二聚体(B)和来自拟杆菌的六聚体BtDyP(C)的示意图。单体中特有的β-Sheet基序以红色突出显示。血红素分子被描绘成灰色的棒状,其中心的铁原子被描绘成一个棕色的球体。PDB代码:4AU9、2IIZ和2GVK。 (附图以PyMOL.1拟备) 关键词: 邻苯二酚类染料; 酶; 糖蛋白; 亚铁血红素; 铁; 远程电子转移; 锰; 过氧化氢; 过氧化物酶; 酪氨酸
The fairly recently discovered dye-decolorizing peroxidases (DyPs) form a distant lineage within the large group of heme peroxidases. DyPs catalyze, inter alia, the degradation of complex anthraquinone dyes. Their structure is predominantly helical with a prominent β-sheet fold, a motif with no equivalent in other heme peroxidases. Lately, intensified research has revealed that the DyP superfamily is widespread in microorganisms and a lot more multifaceted with regard to function than previously imagined. This overview gives an up-to-date account on DyP-type peroxidases and their known biological, chemical, and structural features. 3D Structure Schematic representation of monomeric AauDyP from Auricularia auricula-judae (a), a dimer of TyrA from Shewanella oneidensis (b), and of hexameric BtDyP from Bacteroides thetaiotaomicron (c). The characteristic β-sheet motif is highlighted in red in the monomer. Heme molecules are depicted as grey sticks, their central iron atom as a brown sphere. PDB codes: 4AU9, 2IIZ, and 2GVK.
