In this study, we report the rational design, expression, and functional characterization of novel artilysins derived from P19_358 lysin, a glycoside hydrolase family 24 enzyme. The native P19_358 lysin exhibits limited antibacterial activity, primarily against\n                    <jats:italic>Bacillus subtilis<\/jats:italic>\n                    , and requires EDTA pre\u2010treatment to act against Gram\u2010negative bacteria. To overcome this limitation, C\u2010terminal fusion constructs were engineered using polycationic peptides, including a Cecropin A\u2010derived peptide fragment and polycationic nonapeptide (PCNP), with and without flexible glycine\u2010serine linkers. Structural and biophysical analyses confirmed that peptide fusion did not interfere with the native catalytic domain. Functional assays demonstrated that the engineered artilysins exhibited enhanced antibacterial activity and an expanded host range compared to the native enzyme. Among these constructs, Cecropin A fused artilysins (Art1 and Art2) showed the highest bactericidal activity, achieving up to ~5.4 log\n                    <jats:sub>10<\/jats:sub>\n                    reductions in\n                    <jats:italic>B. subtilis<\/jats:italic>\n                    MTCC 121\u2009\n                    <jats:sup>T<\/jats:sup>\n                    and ~4.9 log\n                    <jats:sub>10<\/jats:sub>\n                    reductions in\n                    <jats:italic>B. pumilus<\/jats:italic>\n                    MTCC 1640\u2009\n                    <jats:sup>T<\/jats:sup>\n                    and\n                    <jats:italic>B. licheniformis<\/jats:italic>\n                    MTCC 429\u2009\n                    <jats:sup>T<\/jats:sup>\n                    . Additionally, Art2 exhibited pronounced antibiofilm activity, significantly reducing biofilm formation across the tested\n                    <jats:italic>Bacillus<\/jats:italic>\n                    species. Stability studies revealed that Art2 possessed superior thermal, pH, and salinity tolerance compared to the native lysin, retaining activity across a broad range of environmental conditions. These findings demonstrate that rational artilysin engineering can substantially enhance antibacterial potency, spectrum, and stability while preserving enzymatic function. Notably, Art2 emerges as a promising candidate for further development as a robust antimicrobial agent with potential applications in food safety and clinical settings.\n                  <\/jats:p>","DOI":"10.1002\/bit.70293","type":"journal-article","created":{"date-parts":[[2026,7,7]],"date-time":"2026-07-07T04:54:07Z","timestamp":1783400047000},"page":"2788-2801","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Polycationic Peptide Engineering of Phage Endolysins Expands Host Range and Enhances Antibacterial and Antibiofilm Activities Against\n                    <i>Bacillus<\/i>\n                    Species"],"prefix":"10.1002","volume":"123","author":[{"given":"Farhat","family":"Ansari","sequence":"first","affiliation":[{"name":"Food Technology Division, Bhabha Atomic Research Centre Mumbai India"},{"name":"Homi Bhabha National Institute Mumbai India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"family":"Tarushi","sequence":"additional","affiliation":[{"name":"Homi Bhabha National Institute Mumbai India"},{"name":"Protein Crystallography Section, Bhabha Atomic Research Centre Mumbai India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6556-8068","authenticated-orcid":false,"given":"Vandan","family":"Nagar","sequence":"additional","affiliation":[{"name":"Food Technology Division, Bhabha Atomic Research Centre Mumbai India"},{"name":"Homi Bhabha National Institute Mumbai India"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,7,6]]},"reference":[{"key":"e_1_2_11_2_1","doi-asserted-by":"publisher","DOI":"10.1128\/AEM.01515-21"},{"key":"e_1_2_11_3_1","doi-asserted-by":"publisher","DOI":"10.4161\/bact.1.2.15845"},{"key":"e_1_2_11_4_1","doi-asserted-by":"publisher","DOI":"10.1038\/s41586-024-07487-w"},{"key":"e_1_2_11_5_1","doi-asserted-by":"publisher","DOI":"10.3390\/antibiotics14121285"},{"key":"e_1_2_11_6_1","doi-asserted-by":"publisher","DOI":"10.1111\/1751-7915.70289"},{"key":"e_1_2_11_7_1","doi-asserted-by":"publisher","DOI":"10.1177\/153537020623100402"},{"key":"e_1_2_11_8_1","doi-asserted-by":"publisher","DOI":"10.1128\/mbio.01379-14"},{"key":"e_1_2_11_9_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.freeradbiomed.2021.11.016"},{"key":"e_1_2_11_10_1","doi-asserted-by":"publisher","DOI":"10.3389\/fmicb.2024.1454618"},{"key":"e_1_2_11_11_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ijmm.2010.04.002"},{"key":"e_1_2_11_12_1","doi-asserted-by":"crossref","unstructured":"Froger A. andJ.
