Webb6 feb. 2024 · Wcw_0377, the W. chondrophila homolog of CT460 possesses the same SWIB/MDM2 domain and was recently demonstrated to reach the host cell nucleus where it could interact with eukaryotic histones . The SWIB/MDM2 domain is mainly present in eukaryotic proteins and rarely found in bacterial proteins [ 35 ], suggesting that proteins … WebbMicrofossil evidence suggests that eukaryotes arose sometime between 1.6 and 2.2 billion years ago. The descendants of this ancient engulfed cell are present in all eukaryotic cells today as mitochondria. We’ll discuss the endosymbiotic theory for the origin of eukaryotes more in the next reading.
