Remark
FUNCTION
  - PHYSIOLOGICAL-ROLE: Active transport of nitrate
  - PROTEIN-FUNCTION: ATP-binding protein 'DED: similarity with 
Synechococcus sp. PCC 7942 'REF: Aichi et al. 2001
PROTEIN-FAMILY: Super-family of ABC transporters 
LOCALIZATION/STRUCTURE:
REGULATION
  - OPERON-STRUCTURE:  nrtABCD-narB (nrtABCD-ssl2814-narB) `EXP: Northern 
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. 2001
  - REGULATOR: NtcA binding site, 20 bp upstream from the -10 promoter 
selement of nrtA `EXP `REF: Aichi et al. 2001
  - PROMOTER: promoter contained an inverted repeat carrying a LysR motif 
(TN11A), centered at position -24 with respect to the NtcA-binding motif 
ssupposed to constitute the binding site for NtcB `REF: Aichi et al. 2001
EXPRESSION: The expression of nrtABCD-narB is repressed by ammonium and 
induced by inhibition of ammonium assimilation, suggesting involvement of 
NtcA. / Under inducing conditions, expression of the transcription unit is 
senhanced by nitrite, suggesting regulation by NtcB. `REF: Aichi et al. 2001
MUTANTS:
GENERAL COMMENT: Synergistic regulation of bicarbonate and nitrate 
transport `HYP `REF: Koropatkin et al. 2006
