description: This entry includes archaeal Zinc-ribbon containing proteins which are mostly uncharacterised.
  Some members of this entry have been described as OapC/ArvC, encoded by oapC gene which is part of the
  three-gene cluster oapABC, involved in generation of extracellular vesicles (arv, archaeal vesiculating
  GTAse). Knockout of OapC/ArvC leads to over vesiculation, possibly due to dysregulation of OapA/ArvA,
  a small GTPase, therefore, it has been suggested that OapC/ArvC may represent a GAP [[cite:PUB00154442],[cite:PUB00154443]].
