Title: Crystallization and preliminary X-ray diffraction of the Munc18c–syntaxin4{sub 1–29} complex

Abstract

Cocrystallization with a peptide, free-interface diffusion crystal chips and crystal dehydration were important in the production of diffraction-quality crystals of the Munc18c protein that helps to regulate membrane fusion. The production of diffraction-quality crystals of Munc18c, a protein involved in regulating vesicular exocytosis in mammals, is reported. The diffraction resolution of Munc18c crystals was optimized by (i) cocrystallizing with a peptide fragment of the Munc18c functional binding partner syntaxin4, (ii) using nanolitre free-interface diffusion crystallization-screening chips and microlitre hanging-drop vapour diffusion and (iii) applying a post-crystallization dehydration treatment. Crystals belonging to the cubic space group P2{sub 1}3, with unit-cell parameters a = b = c = 170.8 Å, α = β = γ = 90°, were generated that diffract to 3.7 Å resolution on a laboratory X-ray source.
