Concept explainers

Mitochondrial Mutations

A mitochondrion is a cellular organelle that serves as the site for cellular respiration and energy production (ATP or Adenosine Triphosphate). It is a double-membrane-bound organelle and is only present in eukaryotic cells.

Explain how mutations in mitochondrial genes cause human
diseases

Expert Solution

Step 1

Several mitochondrial diseases in humans occur due to mutations in mitochondrial genes. These mutations usually cause chronic degenerative disorders that affect cells requiring a high level of ATP, such as nerve, and muscle cells.

Many clinically relevant mitochondrial diseases are caused by mutations in mitochondrial genes affecting tRNAs. For example, one form of MELAS (mitochondrial myopathy, encephalopathy, lactic acidosis and stroke-like episodes) is caused by a point mutation in the gene encoding the mitochondrial tRNA whose anticodon recognizes the codons 5' UUA and 5' UUG. The mutation makes the aminoacylation of this tRNA inefficient. a. The rate of synthesis of most mitochondrial proteins is either unaffected or slightly decreased in MELAS cells, but one mitochondrial protein called NAD6 is synthesized at only 10% of the normal rate. How is it possible that the translation of this single mitochondrial protein might be affected specifically?
1. Peroxisomes are organelles surrounded by a single membrane. Soluble proteins that reside within peroxisomes are imported post-translationally, and they often contain the C-terminal tripeptide SKL (serine-lysine-leucine). a) How would you confirm that a C-terminal SKL tripeptide is a peroxisomal targeting signal? b) If cells were engineered to produce a hybrid protein consisting of a mitochondrial matrix protein (including its signal sequence) followed by a C-terminal SKL signal, where in the cell would you expect the hybrid protein to be found? Explain your reasoning.
