The Succinate Dehydrogenase Genes of the Silkworm, Bombyx mori

Article Preview

Abstract:

The succinate sehydrogenase (SDH) encoded by nuclear genome is a conjugating enzyme in the inner mitochondrial membrane. It is a junction for oxidative phosphorylation and the electron transport chain.As a part of complex II on the inner mt membranes, the SDH consists of four subunit proteins (A to D). We searched the genome sequence database of Bombyx mori with the Drosophila melanogaste and Nasonia vitripennis SDH by tBlastn and determined the structure of all putative B. mori genes of sdh by DNAMAN. The main results are as follows: The SdhAgene of B. mori contains 13 exons. The lengths of its cDNA is 2 880 bp at least. The SdhB gene of B. mori contains 1 exon only. The lengths of cDNA is 2 847 bp at least. The SdhC gene contains 4 exons. The lengths of cDNA is 714 bp at least. The SdhD gene contains 4 exons, too. The lenghts of cDNA is 1 976 bp at least.
