1.14.15.3 2D crystallization 724025 1.14.15.3 homology miodeling of structure and docking of octane, octanol and 1-octyne. Residues Ala53, Trp55, Val15 and Tyr339 of AlkB are involved in the octane uptake/binding, octanol binding/exit, and the 1-octyne uptake/binding 745577 1.14.15.3 molecular modeling of the transmembrane domain 744267 1.14.15.3 to 3.1 A resolution, the alkane-like substrate is in the hydrophobic pocket containing residues Thr74, Met90, Ala175, Ile240, Leu241, Val244, Leu292, Met295, and Phe393. Conformational changes in the beta1-beta2, alpha3-alpha4 and alpha6-alpha7 connecting loop are important for incorporating the long hydrophobic substrate 745115
