Hypothetical Evolutionary Event

Duplication-fusion event in the archaeal histone-fold protein HMk (16)

Duplication-fusion event in the archaeal histone-fold protein HMk. The histone domain contains two tandem histone fold repeats arranged as in the histone dimer. This event is similar to the event that have occurred in Son of Sevenless protein and bacterial histone-fold proteins.
