Claim: The NDUFA11 gene is located on the p arm of chromosome 19, it  produces a 15 kDa protein and is a subunit of an enzyme a biocatalyst.
Evidence: The NDUFA11 gene is located on the p arm of chromosome 19 in position 13.3 and spans 12,738 base pairs. The gene produces a 15 kDa protein composed of 141 amino acids. NDUFA11 is a subunit of the enzyme NADH dehydrogenase (ubiquinone), the largest of the respiratory complexes. Enzymes /ˈɛnzaɪmz/ are proteins that act as biological catalysts (biocatalysts).
