FUNCTIONs  - PHYSIOLOGICAL-ROLE: Active transport of nitrate s  - PROTEIN-FUNCTION: permease protein 'DED: similarity with Synechococcus ssp. PCC 7942 'REF: Aichi et al. 2001sPROTEIN-FAMILY: Super-family of ABC transporters sLOCALIZATION/STRUCTURE: -sREGULATIONs  - OPERON-STRUCTURE:  nrtABCD-narB (nrtABCD-?ssl2814?-narB in CYORF) `EXP: sNorthern hybridization nrtC-specific probe indicated the presence of a slarge transcription unit / narB-specific probe yielded essentially the same shybridization profile / the size of the largest signal was close to the scalculated size of the nrt-ABCD-narB gene cluster. `REF: Aichi et al. 2001s  - REGULATOR: NtcA binding site, 20 bp upstream from the -10 promoter selement of nrtA `EXP `REF: Aichi et al. 2001s  - PROMOTER: promoter contained an inverted repeat carrying a LysR motif s(TN11A), centered at position -24 with respect to the NtcA-binding motif ssupposed to constitute the binding site for NtcB `REF: Aichi et al. 2001s  - EXPRESSION: The expression of nrtABCD-narB is repressed by ammonium and sinduced by inhibition of ammonium assimilation, suggesting involvement of sNtcA. / Under inducing conditions, expression of the transcription unit is senhanced by nitrite, suggesting regulation by NtcB. `REF: Aichi et al. 2001sMUTANTS: -sOTHER COMMENTS: `HYP: synergistic regulation of bicarbonate and nitrate stransport `REF: Koropatkin et al. 2006
