- * Bacterial regulatory proteins, gntR family signature *
- ********************************************************
-
- The many bacterial transcription regulation proteins which bind DNA through a
- 'helix-turn-helix' motif can be classified into subfamilies on the basis of
- sequence similarities. One of these subfamilies groups together [1,2,3]:
-
- - fadR from Escherichia coli, a multifunctional regulator of fatty acid
- metabolism.
- - gntR from Bacillus subtilis, the transcriptional repressor of the gluconate
- operon.
- - hutC, Klebsiella aerogenes and Pseudomonas putida transcriptional repressor
- of the histidine utilization (hut) operon.
- - korA from Streptomyces lividans plasmid pIJ101, a regulator protein that
- controls plasmid transfer.
- - lctR from Escherichia coli, a putative regulator of the L-lactate
- dehydrogenase operon.
- - phdR from Escherichia coli, the transcriptional repressor of the pyruvate
- dehydrogenase complex.
- - phnF from Escherichia coli, a putative transcriptional regulator of the phn
- locus which encodes proteins involved in alkylphosphonate uptake and
- cleavage of the carbon-phosphorus bond.
- - Escherichia coli protein P30, a possible transcriptional regulator of the
- succinyl-CoA-synthetase operon.
- - yidP, an Escherichia coli hypothetical protein.
- - yihL, an Escherichia coli hypothetical protein.
-
- The 'helix-turn-helix' DNA-binding motif of these proteins is located in the
- N-terminal part of the sequences. The pattern we use to detect these proteins
- spans the complete helix-turn-helix motif.
-
- -Consensus pattern: E-x(2)-[LIVM]-x(3)-[LIVMF]-x-[LIVMF]-[NSTK]-R-x(2)-[LIVM]-
- x(3)-[LIVM]-x(2)-L
- -Sequences known to belong to this class detected by the pattern: ALL, except
- for korA.
- -Other sequence(s) detected in SWISS-PROT: Turnip Yellow Mosaic virus RNA
- replicase polyprotein.
