Function

[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.^[1] ^[2] ^[3] ^[4]

Publication Abstract from PubMed

The influx of genomic sequence information has led to the concept of structural proteomics, the determination of protein structures on a genome-wide scale. Here we describe an approach to structural proteomics of small proteins using NMR spectroscopy. Over 500 small proteins from several organisms were cloned, expressed, purified, and evaluated by NMR. Although there was variability among proteomes, overall 20% of these proteins were found to be readily amenable to NMR structure determination. NMR sample preparation was centralized in one facility, and a distributive approach was used for NMR data collection and analysis. Twelve structures are reported here as part of this approach, which allowed us to infer putative functions for several conserved hypothetical proteins.
