Family level classification of domain no. 4 from sequence Q8U0H4

Uncertain (marginal E-value): The Intein endonuclease family has an E-value of 0.041 for the domain selected. This score is conditional on the domain being a member of the Homing endonucleases superfamily. There is a possibility that the selected domain is the member of a sub-family for which no structure has yet been solved.

1dq3 A:227-335 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 1dq3 A:227-335.
