In tailed phages, this process is driven by a packaging motor composed of a portal protein and a terminase complex. The terminase complex usually consists of a large subunit (TerL) and a small subunit (TerS), which cooperate to recognize, cleave, and translocate genomic DNA into the capsid. However, due to the remarkable diversity and complexity of phage packaging systems, the molecular mechanisms governing TerS-mediated DNA recognition remain poorly understood. Here, we report the 3.51 Å cryo-electron microscopy structure of the TerS from the short-tailed cyanophage Pam5, which infects the host <i>Pseudanabaena mucicola</i> Chao 1806. Pam5 TerS assembles into a nonameric ring with a radially symmetric spiral architecture. Biochemical assays show that Pam5 TerS recognizes the genomic DNA via a specific interaction between the N-terminal helix-turn-helix (HTH) domain of TerS and a 21-bp DNA sequence within the <i>terS</i> gene. In contrast, the TerS from another short-tailed cyanophage, Pam1, which infects the same host, binds to DNA in a sequence-independent manner. These findings reveal that cyanophages, even infecting the same host, could adopt two distinct DNA recognition strategies: HTH-mediated sequence-dependent or sequence-independent modes.

Accordingly, AAV9-mediated PHB2 overexpression exhibits therapeutic effects in a mouse model of pulmonary fibrosis. We also observe significant downregulation of PHB2 in IPF lungs. Functionally, PHB2 attenuates fibroblast migration and counteracts the TGF-β1-induced enhancement of mitochondrial respiration in lung fibroblasts.
