Metal ion-interacting network of UPs. (a) Superimposition of the metal ion-interacting network of PcUP1 with other UPs. PcUP1 is colored cyan; TbUP is colored yellow; EcUP is colored magenta; HsUPP1 is colored salmon. The shown residues are strictly conserved or semi-conserved. (b) Effects of different metal ions and mutational protein on PcUP1 activity. The production levels of URA by each protein are presented as percentages of the wild type. Each measurement was conducted in triplicate, from which the average ± s.d. was calculated.
