Figure 3
Monomer contacts in an asymmetric unit. (a) IL-3A dUTPase. Two monomers were seen. Dotted trapezoids represent a trimer molecule. Solid figures labeled A and B represent the two monomers (chains). Polar contacts between monomers A and B (dotted circle) are listed on the right. (b) Mu-22 dUTPase. One trimer and one monomer were seen. Solid figures labeled A, B, C and D represent the monomers. Monomer A and the trimer composed of monomers B, C and D are connected by dUDP (small solid circle). Polar contacts between monomer A and trimer BCD (dotted circle) are listed on the right. Dotted squares indicate the locations of the C-termini. |
