Sequence comparison of herpesvirus homologs allowed us to identify a potential LATLNDIERFL and zinc finger pattern in N-terminal part of pUL56. Recombinant viruses were generated with specific serine or alanine substitutions in these putative patterns. We identified a LATLNDIERFL pattern characteristic of LAGLIDADG homing endonucleases and a metal-binding pattern involving the cysteine and histidine residues C191-X2-C194-X22-C217-X-H219 (CCCH) close to the region conferring letermovir resistance. These patterns are crucial for viral replication, suggesting that they are essential for pUL56 structure and function. Thus, these patterns represent potential targets for the development of new antivirals such as small molecules or peptides and may allow to better understand the letermovir mechanism of action.<\/jats:p>","DOI":"10.3390\/v11121093","type":"journal-article","created":{"date-parts":[[2019,11,26]],"date-time":"2019-11-26T10:57:27Z","timestamp":1574765847000},"page":"1093","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":11,"title":["Highlighting of a LAGLIDADG and a Zing Finger Motifs Located in the pUL56 Sequence Crucial for HCMV Replication"],"prefix":"10.3390","volume":"11","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1237-1936","authenticated-orcid":false,"given":"Ga\u00ebtan","family":"Ligat","sequence":"first","affiliation":[{"name":"UMR 1092, INSERM, CHU Limoges, Universit\u00e9 Limoges, F-87000 Limoges, France"},{"name":"Laboratoire de Bact\u00e9riologie-Virologie-Hygi\u00e8ne, National Reference Center for Herpesviruses (NRCHV), CHU Limoges, F-87000 Limoges, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anthony","family":"Couvreux","sequence":"additional","affiliation":[{"name":"UMR 1092, INSERM, CHU Limoges, Universit\u00e9 Limoges, F-87000 Limoges, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rapha\u00ebl","family":"Cazal","sequence":"additional","affiliation":[{"name":"UMR 1092, INSERM, CHU Limoges, Universit\u00e9 Limoges, F-87000 Limoges, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sophie","family":"Alain","sequence":"additional","affiliation":[{"name":"UMR 1092, INSERM, CHU Limoges, Universit\u00e9 Limoges, F-87000 Limoges, France"},{"name":"Laboratoire de Bact\u00e9riologie-Virologie-Hygi\u00e8ne, National Reference Center for Herpesviruses (NRCHV), CHU Limoges, F-87000 Limoges, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2635-0773","authenticated-orcid":false,"given":"S\u00e9bastien","family":"Hantz","sequence":"additional","affiliation":[{"name":"UMR 1092, INSERM, CHU Limoges, Universit\u00e9 Limoges, F-87000 Limoges, France"},{"name":"Laboratoire de Bact\u00e9riologie-Virologie-Hygi\u00e8ne, National Reference Center for Herpesviruses (NRCHV), CHU Limoges, F-87000 Limoges, France"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2019,11,26]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"566","DOI":"10.1002\/jmv.20127","article-title":"Detection of ganciclovir resistance after valacyclovir-prophylaxis in renal transplant recipients with active cytomegalovirus infection","volume":"73","author":"Alain","year":"2004","journal-title":"J.
