Abstract (EN): A 31-kDa subunit of complex I from Neurospora crassa, of nuclear origin, was cloned. The precursor polypeptide (33 kDa) could be efficiently expressed in an in vitro system for transcription and translation. The processing of the precursor to the mature protein was also obtained in vitro. An open reading frame coding for a precursor protein of 283 amino acids (32247 Da) was found by DNA sequencing. The predicted primary structure shows significant homology with proteins made in chloroplast. This supports the hypothesis that an enzyme similar to respiratory chain NADH dehydrogenase might exist in these organelles. © 1990.
