The search space for protein engineering grows exponentially with complexity. A protein of just 100 amino acids has 20^100 possible variants-more combinations than atoms in the observable universe.

A change in the DNA sequence of a codon may not change the corresponding amino acid residue in the encoded protein because each residue can be encoded by several codons. This is called the Wobble ...

Genetic disorders — like cystic fibrosis and Huntington’s disease — are considered incurable, with gene mutations occurring in essentially every cell of the body. Gene mutations occur when one ...

Researchers have developed the first mouse model for a mitochondrial tRNALeu mutation, showing that the associated metabolic disorder results from faulty RNA processing. Studying the role of ...

Researchers at UCL and MRC London Institute of Medical Sciences have demonstrated that reducing naturally occurring errors in protein synthesis improves both health and lifespan in different model ...

tRNAs have a distinct cloverleaf secondary structure and an L-shaped tertiary structure. The cloverleaf structure is formed by the folding of the single-stranded tRNA molecule, which is typically ...

Researchers are adding new evidence to the emerging concept that 'silent' or synonymous mutations may have crucial consequences. Their study showed how a synonymous mutation in one gene can ...

Tsukuba, Japan—Studying the role of mitochondria—the specialized structures within cells responsible for energy production—in metabolic diseases has been difficult because of a lack of animal models ...
