Fig. 2From: Evaluation of vector systems and promoters for overexpression of the acarbose biosynthesis gene acbC in Actinoplanes sp. SE50/110Current model of acarbose biosynthesis according to protein homologies and functional predictions [6, 11, 13]. The first three steps, catalyzed by AcbC, AcbM and AcbO (shown in blue), were experimentally proven [7, 11, 12]Back to article page
