Hachiman antiphage defense system has been described in Ralstonia solanacearum species complex (RSSC), and is composed of two genes, hamAB, which encode a protein of unknown function HamA, represented in this entry, and an helicase (HamB). Only one strain (KACC10722) from phylotype IV shows this system complete and both genes are organised in an operon [1,2].	Domain

Members of this family include the DEAD and DEAH box helicases. Helicases are involved in unwinding nucleic acids. The DEAD box helicases are involved in various aspects of RNA metabolism, including nuclear transcription, pre mRNA splicing, ribosome biogenesis, nucleocytoplasmic transport, translation, RNA decay and organellar gene expression.	Domain
B	PF00271	Helicase conserved C-terminal domain (Helicase_C)	Helicase conserved C-terminal domain	The Prosite family is restricted to DEAD/H helicases, whereas this domain family is found in a wide variety of helicases and helicase related proteins. It may be that this is not an autonomously folding unit, but an integral part of the helicase.	Domain
