The burst size was 96 PFU/cell after 30 min of latent period and 90 min of rising period. Phage YZU-L1 could maintain high activity at pH of 4-13, and resist 50 °C for up to 60 min.
WebPhage T4 terminase is a two-subunit enzyme that binds to the prohead portal protein and cuts and packages a headful of concatameric DNA. To characterize the T4 terminase large subunit, gp17 (70 kDa), gene 17 was cloned and expressed as a chitin-binding fusion protein. Following cleavage and release of gp17 from chitin, two additional column steps … Web7 Apr 2024 · When the phage head is full, the portal detects internal pressure and conveys a signal from the inner capsid to the exterior, which triggers a sequence of events—the …
Web15 Sep 2002 · In phage T4, the small terminase subunit is encoded by the 18 kDa gp16 and the large terminase subunit by the 70 kDa gp17 (6, 7). gp17 exhibits an endonuclease activity, an in vitro DNA packaging activity and an ATPase activity, whereas gp16 lacks any of these activities but stimulates the latter two activities associated with gp17 (8, 9).
