Family level classification of domain no. 1 from sequence A1A4Q9

The MutT-like family has an E-value of 0.00000521 for the domain selected. This score is conditional on the domain being a member of the Nudix superfamily.

1u20 A:14-209 is the closest structural domain in the library. There may be other structures not included in the library that are closer, but those structures will be more than 95% identical in sequence to 1u20 A:14-209.
