Oligomer structures of dopamine beta-hydroxylase

Ribbon diagram (Richardson diagram) of dopamine beta-hydroxylase. (A) Model for the dimeric form of dopamine beta-hydroxylase. Chains A and B are shown in blue and red, respectively. (B) Model for the tetrameric form of the enzyme. Chains A, B, C, and D are depicted in blue, red, green and purple, respectively. (C) Residues forming a tetramer interface. Subunits are highlighted in tube conformation with chains A, B, C, and D highlighted in blue, red, green and yellow, respectively. Residues are represented with the same colors as that of the corresponding chain color. (Source: Kapoor A, Shandilya M, Kundu S.
