Research Abstract |
We found that a 50S ribosomal protein L2 was purified as a complex with His-tagged HtpG from Escherichia coli cultured in minimum medium at 45oC. L2 specifically activated ATPase of HtpG more than ten-fold. HtpG was also found in fractions of 30S and 50S ribosome subunits in vivo. These results suggested that HtpG associates with various ribosomal proteins including L2 as a client protein and contributes for ribosome biogenesis.
