Function[DEF1_AESHI] Possesses antimicrobial activity sensitive to inorganic cations. Binds specifically to the fungal plasma membrane. Has no inhibitory effect on insect gut alpha-amylase.[1] [2] 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 PubMedAesculus hippocastanum antimicrobial protein 1 (Ah-AMP1) is a plant defensin isolated from horse chestnuts. The plant defensins have been divided in several subfamilies according to their amino acid sequence homology. Ah-AMP1, belonging to subfamily A2, inhibits growth of a broad range of fungi. So far, a three-dimensional structure has been determined only for members of subfamilies A3 and B2. In order to understand activity and specificity of these plant defensins, the structure of a protein belonging to subfamily A2 is needed. We report the three-dimensional solution structure of Ah-AMP1 as determined from two-dimensional 1H nuclear magnetic resonance data. The structure features all the characteristics of the "cysteine-stabilized alpha beta-motif." A comparison of the structure, the electrostatic potential surface and regions important for interaction with the fungal receptor, is made with Rs-AFP1 (plant defensin of subfamily A3). Thus, residues important for activity and specificity have been assigned. The three-dimensional solution structure of Aesculus hippocastanum antimicrobial protein 1 determined by 1H nuclear magnetic resonance.,Fant F, Vranken WF, Borremans FA Proteins. 1999 Nov 15;37(3):388-403. PMID:10591099[3] From MEDLINE®/PubMed®, a database of the U.S. National Library of Medicine. See AlsoReferences
