a charged performance by gp17 in viral packaging.packaging of viral genomes into virus capsids requires powerful motors to overcome the repulsive force that builds as the nucleic acids are compressed. through structural analyses of the t4 bacteriophage packaging motor gp17, sun et al. (2008) now propose a packaging mechanism in which electrostatic forces cause the motor to alternate between tensed and relaxed conformational states.200819109888
the structure of the phage t4 dna packaging motor suggests a mechanism dependent on electrostatic forces.viral genomes are packaged into "procapsids" by powerful molecular motors. we report the crystal structure of the dna packaging motor protein, gene product 17 (gp17), in bacteriophage t4. the structure consists of an n-terminal atpase domain, which provides energy for compacting dna, and a c-terminal nuclease domain, which terminates packaging. we show that another function of the c-terminal domain is to translocate the genome into the procapsid. the two domains are in close contact in the cryst ...200819109896
