The hepatitis C protein NS3 acts as both a protease and as one of these proteins.
The hepatitis C protein NS3 acts as both a protease and as one of these proteins. The nuclear protein Mtr4p and the mitochondrial protein Suv3p are examples of the Ski2 family of these proteins. They're not dyneins or kinesins, but the "rolling" and "inchworm" models are proposed mechanisms for one of these proteins called PcrA. One type of these proteins contains a Q motif to control ATP binding as well as a Walker B motif containing an aspartate- glutamine-alanine-aspartate sequence. One type of these proteins is a hexamer which uses NTP hydrolysis to translocate along its substrate. Examples of these proteins include UvrD, RecQ, DEAD box proteins, and DnaB. These enzymes are loaded onto ori sites, where they break the hydrogen bonds between nucleobases, initiating replication. For 10 points, name these enzymes which generate a replication fork by unwinding double-stranded DNA.
