Abstract

We have developed a simple method for measuring the missense substitution of amino acids at specified positions in proteins synthesized in vivo. We find that the frequency of cysteine substitution for the single arginine in Escherichia coli ribosomal protein L7/L12 is close to 10(-3) for wild-type bacteria, decreases to 4 x 10(-4) in streptomycin-resistant bacteria containing mutant S12 (rpsL), and is virtually unchanged in Ram bacteria containing mutant S4 (rpsD). We have also found that the frequency of the cysteine substitution for the single tryptophan in E. coli ribosomal protein S6 is 3-4 x 10(-3) for wild-type bacteria, decreases to 6 x 10(-4) in streptomycin-resistant bacteria and is elevated to nearly 10(-2) in Ram bacteria.

Cnr interferes with dimerization of the replication protein alpha in phage-plasmid P4.

DNA replication of phage-plasmid P4 in its host Escherichia coli depends on its replication protein alpha. In the plasmid state, P4 copy number is controlled by the regulator protein Cnr (copy number regulation). Mutations in alpha (alpha(cr)) that prevent regulation by Cnr cause P4 over-replication and cell death. Using the two-hybrid system in Saccharomyces cerevisiae and a system based on lambda immunity in E.coli for in vivo detection of protein-protein interactions, we found that (i) alpha protein interacts with Cnr, whereas alpha(cr) proteins do not; (ii) both alpha-alpha and alpha(cr)-alpha(cr) interactions occur and the interaction domain is located within the C-terminal of alpha; (iii) Cnr-Cnr interaction also occurs. Using an in vivo competition assay, we found that Cnr interferes with both alpha-alpha and alpha(cr)-alpha(cr) dimerization. Our data suggest that Cnr and alpha interact in at least two ways, which may have different functional roles in P4 replication control.

Hydrophobic core malleability of a de novo designed three-helix bundle protein.

De novo protein design provides a tool for testing the principles that stabilize the structures of proteins. Recently, we described the design and structure determination of alpha(3)D, a three-helix bundle protein with a well-packed hydrophobic core. Here, we test the malleability and adaptability of this protein's structure by mutating a small, Ala residue (A60) in its core to larger, hydrophobic side-chains, Leu and Ile. Such changes introduce strain into the structures of natural proteins, and therefore generally destabilize the native state. By contrast, these mutations were slightly stabilizing ( approximately 1.5 kcal mol(-1)) to the tertiary structure of alpha(3)D. The value of DeltaC(p) for unfolding of these mutants was not greatly affected relative to wild-type, indicating that the change in solvent accessibility for unfolding was similar. However, two-dimensional heteronuclear single quantum coherence spectra indicate that the protein adjusts to the introduction of steric bulk in different ways. A60L-alpha(3)D showed serious erosion in the dispersion of both the amide backbone as well as the side-chain methyl chemical shifts. By contrast, A60I-alpha(3)D showed excellent dispersion of the backbone resonances, and selective changes in dispersion of the aliphatic side-chains proximal to the site of mutation. Together, these data suggest that alpha(3)D, although folded into a unique three-dimensional structure, is nevertheless more malleable and flexible than most natural, native proteins.

Substitution of Asp114 or Arg116 in the fingers domain of moloney murine leukemia virus reverse transcriptase affects interactions with the template-primer resulting in decreased processivity.

Reverse transcriptase, an essential retroviral DNA polymerase, replicates the single-stranded RNA genome of the retrovirus, producing a double-stranded DNA copy, which is subsequently integrated into the host's genome. Substitution of Ala for either Asp114 or Arg116, two highly conserved residues in the fingers domain of Moloney murine leukemia virus reverse transcriptase, results in enzymes (D114A or R116A) with significant defects in their abilities to processively synthesize DNA using RNA or DNA as a template. D114A and R116A enzymes also bind more weakly to template-primer in the presence of added deoxyribonucleotides, as seen by gel-shift analysis, but retain the ability to strand transfer and accumulate smaller RNase H cleavage products when compared to the wild-type enzyme. In addition, mutant proviruses, including D114A and R116A substitutions in Moloney murine leukemia virus reverse transcriptase, are not viable despite the presence of processed reverse transcriptase in the viral particles. A potential mechanistic role in processive synthesis for D114 and R116 is discussed in the context of our results, related studies on HIV-1 reverse transcriptase, and previous structural studies.
