The structure of an Escherichia coli tRNA(Ser) acceptor stem microhelix was solved by high resolution X-ray structure analysis. The RNA crystallizes in the space group C2, with one molecule per asymmetric unit and with the cell constants a=35.79, b=39.13, c=31.37A, and beta=111.1 degrees . A defined hydration pattern of 97 water molecules surrounds the tRNA(Ser) acceptor stem microhelix. Additionally, two magnesium binding sites were detected in the tRNA(Ser) aminoacyl stem.
