While the structure of the HblB component of this toxin is known, the structures of the other components are unresolved. Here, we describe the expression of the recombinant HblL1 component and the elucidation of its structure to 1.36 \u00c5. Like HblB, it is a member of the alpha-helical pore-forming toxin family. In comparison to other members of this group, it has an extended hydrophobic beta tongue region that may be involved in pore formation. Molecular docking was used to predict possible interactions between HblL1 and HblB, and suggests a head to tail dimer might form, burying the HblL1 beta tongue region.<\/jats:p>","DOI":"10.3390\/toxins13040253","type":"journal-article","created":{"date-parts":[[2021,3,31]],"date-time":"2021-03-31T10:24:33Z","timestamp":1617186273000},"page":"253","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":13,"title":["The Crystal Structure of Bacillus cereus HblL1"],"prefix":"10.3390","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8497-0773","authenticated-orcid":false,"given":"Harley L.","family":"Worthy","sequence":"first","affiliation":[{"name":"School of Biosciences, Cardiff University, Park Place, Cardiff CF10 3AX, UK"},{"name":"The Henry Wellcome Building for Biocatalysis, Exeter University, Stocker Road, Exeter EX4 4QD, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3575-5078","authenticated-orcid":false,"given":"Lainey J.","family":"Williamson","sequence":"additional","affiliation":[{"name":"School of Biosciences, Cardiff University, Park Place, Cardiff CF10 3AX, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1086-741X","authenticated-orcid":false,"given":"Husam Sabah","family":"Auhim","sequence":"additional","affiliation":[{"name":"School of Biosciences, Cardiff University, Park Place, Cardiff CF10 3AX, UK"},{"name":"Department of Biology, College of Science, University of Baghdad, Baghdad, Iraq"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Stephen H.","family":"Leppla","sequence":"additional","affiliation":[{"name":"Laboratory of Parasitic Diseases, National Institute of Allergy and Infectious Diseases, National Institutes of Health, Bethesda, MD 20892, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Inka","family":"Sastalla","sequence":"additional","affiliation":[{"name":"Laboratory of Parasitic Diseases, National Institute of Allergy and Infectious Diseases, National Institutes of Health, Bethesda, MD 20892, USA"},{"name":"Scientific Review Program, Division of Extramural Activities, NIAID, NIH, Rockville, MD 20892, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7709-3995","authenticated-orcid":false,"given":"D.
