摘要

二异丙基氟磷酸酶(DFPase)是一种钙依赖性磷酸三酯酶，能够水解多种有毒有机磷化合物中的磷-氟键，报道了DFPase的主链(15N, 1H)和部分侧链(13Cα和β，侧链1H)原子的核磁共振化学位移分配。对DFPase活性位点的残基进行分析，发现一些残基的化学位移可以作为有机磷化合物结合的诊断和检测。

Backbone and side chain chemical shift assignment of diisopropyl fluorophosphatase (DFPase) from Loligo vulgaris, an organophosphorus-degrading enzyme

NMR chemical shift assignments are reported for backbone (¹⁵N, ¹H) and partial side chain (¹³Cα and β, side chain ¹H) atoms of diisopropyl fluorophosphatase (DFPase), a calcium-dependent phosphotriesterase capable of hydrolyzing phosphorus – fluorine bonds in a variety of toxic organophosphorus compounds. Analysis of residues lining the active site of DFPase highlight a number of residues whose chemical shifts can be used as a diagnostic of binding and detection of organophosphorus compounds.

期刊介绍： Biomolecular NMR Assignments provides a forum for publishing sequence-specific resonance assignments for proteins and nucleic acids as Assignment Notes. Chemical shifts for NMR-active nuclei in macromolecules contain detailed information on molecular conformation and properties. Publication of resonance assignments in Biomolecular NMR Assignments ensures that these data are deposited into a public database at BioMagResBank (BMRB; http://www.bmrb.wisc.edu/), where they are available to other researchers. Coverage includes proteins and nucleic acids; Assignment Notes are processed for rapid online publication and are published in biannual online editions in June and December.
