3.1.26.11 dimer gel filtration analysis shows that, only 20% of tRNase Z2 molecules form dimers, while tRNase Z molecules exist as dimers. This inefficient tRNase Z2 dimer formation may be attributed to the lack of alpha1, alpha2, and alpha3 that are important for dimerization of tRNase Z Thermotoga maritima
