Fig. 2From: Aadh2p: an Arxula adeninivorans alcohol dehydrogenase involved in the first step of the 1-butanol degradation pathwayAlignment of Aadh2p sequence with the seven Adhp sequences from S. cerevisiae (ScAdhps). a Structural Zn2+ binding sites are shown framed [9–11], catalytic Zn2+ binding site in grey [9, 10] and NAD+ binding site is underlined [11–13]. b Phylogenetic tree constructed using the neighbour joining method of Aadh2p from A. adeninivorans (Aa) and Adhps from S. cerevisiae (Sc)Back to article page
