A, B	PF09277	Erythronolide synthase, docking (Erythro-docking)	Erythronolide synthase, docking	Members of this family of docking domains are found in prokaryotic erythronolide synthase. They adopt a structure consisting of a bundle of four alpha-helices, and mediate homodimerisation of the protein, stabilising the resulting complex [1].	Domain
