PROSITE documentation PDOC00769 |
A number of bacterial and archaebacterial proteins involved in transporting formate or nitrite have been shown [1] to be related:
These transporters are proteins of about 280 residues and seem to contain six transmembrane regions. As signature patterns, we selected two conserved regions. The first one is located in what seems to be a cytoplasmic loop between the second and third transmembrane domains; the second is part of the fourth transmembrane region.
The 70 Kd yeast hypothetical protein YHL008c is highly similar, in its N-terminal section, to the prokaryotic members of this family.
Note:These proteins belongs to family TC 2.44 in the classification of transporters [2].
