| - | [[ | + | [[https://www.uniprot.org/uniprot/HHA_ECOLI HHA_ECOLI]] Down-regulates hemolysin production and can also stimulate transposition events in vivo. Binds DNA and influences DNA topology in response to environmental stimuli. Involved in persister cell formation, acting downstream of mRNA interferase (toxin) MqsR. Decreases biofilm formation by repressing the transcription of fimbrial genes fimA and ihfA, and by repressing the transcription of tRNAs corresponding to rare codons, which are abundant in type 1 fimbrial genes.<ref>PMID:1956303</ref> <ref>PMID:16317765</ref> <ref>PMID:18545668</ref> <ref>PMID:19909729</ref> [[https://www.uniprot.org/uniprot/HNS_ECOLI HNS_ECOLI]] A DNA-binding protein implicated in transcriptional repression (silencing) as well as in bacterial chromosome organization. H-NS binds tightly to AT-rich dsDNA, increases its thermal stability and inhibits transcription. Also binds to ssDNA and RNA but with a much lower affinity. H-NS has possible histone-like function. May be a global transcriptional regulator through its ability to bind to curved DNA sequences, which are found in regions upstream of a certain subset of promoters. Plays a role in the thermal control of pili and adhesive curli fimbriae production, by inducing transcription of csgD. Represses the CRISPR-cas promoters, permits only weak transcription of the crRNA precursor; its role is antagonized by LeuO. Subject to transcriptional auto-repression. Binds preferentially to the upstream region of its own gene recognizing two segments of DNA on both sides of a bend centered around -150.<ref>PMID:7934818</ref> <ref>PMID:11031114</ref> <ref>PMID:17010156</ref> <ref>PMID:20659289</ref> |
