CRYSTAL STRUCTURE OF BEE-VENOM PHOSPHOLIPASE A2 IN A COMPLEX WITH A TRANSITION-STATE ANALOGUECRYSTAL STRUCTURE OF BEE-VENOM PHOSPHOLIPASE A2 IN A COMPLEX WITH A TRANSITION-STATE ANALOGUE
Structural highlights
Function[PA2_APIME] PLA2 catalyzes the calcium-dependent hydrolysis of the 2-acyl groups in 3-sn-phosphoglycerides. Evolutionary Conservation Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf. Publication Abstract from PubMedThe 2.0 angstroms crystal structure of a complex containing bee-venom phospholipase A2 (PLA2) and a phosphonate transition-state analogue was solved by multiple isomorphous replacement. The electron-density map is sufficiently detailed to visualize the proximal sugars of the enzyme's N-linked carbohydrate and a single molecule of the transition-state analogue bound ot its active center. Although bee-venom PLA2 does not belong to the large homologous Class I/II family that encompasses most other well-studied PLA2s, there is segmental sequence similarity and conservation of many functional substructures. Comparison of the bee-venom enzyme with other phospholipase structures provides compelling evidence for a common catalytic mechanism.
