== Function ==
[https://www.uniprot.org/uniprot/HSLV_ECOLI HSLV_ECOLI] Protease subunit of a proteasome-like degradation complex believed to be a general protein degrading machinery. The complex has been shown to be involved in the specific degradation of heat shock induced transcription factors such as RpoH and SulA. In addition, small hydrophobic peptides are also hydrolyzed by HslV. HslV has weak protease activity even in the absence of HslU, but this activity is induced more than 100-fold in the presence of HslU. HslU recognizes protein substrates and unfolds these before guiding them to HslV for hydrolysis. HslV is not believed to degrade folded proteins.<ref>PMID:8662828</ref> <ref>PMID:8650174</ref> <ref>PMID:9288941</ref> <ref>PMID:9393683</ref> <ref>PMID:10452560</ref> <ref>PMID:10419524</ref> <ref>PMID:15696175</ref>
