We were annotating the following protein, with hits to binding proteins and HTH domain containing proteins.

Checking for HTH on HHpred output wasn't totally clear. In the output below, I've put green boxes around possible HTH regions for both the Query and the Target. The Target has a definite HTH domain. The Query, however, is a little doubtful. One of the helices is only 3 amino acids long, and my understanding is that at least 5 aa's are needed for a stable helix.

Rick Pollenz was consulted and confirmed that there is not a HTH in that protein. He used two programs to investigate:

Thanks Rick!

Our call is going to be DNA binding protein
