  1. RaCDP, cellodextrin phosphorylase from R. albus [21]; CtCDP, cellodextrin phosphorylase from C. thermocellum [22]; CepB, cellodextrin phosphorylase from C. stercorarium [16]. Km value are given in mM, kcat were converted from s−1 to min−1, and kcat/Km values were calculated in min−1 mM−1. nd, not determined
