Nucleotide sequence of the PetM gene encoding a 4 kDa subunit of the cytochrome b6f complex from Chlamydomonas reinhardtii

摘要

We have determined the nucleotide sequence of the PetM gene from the single celled alga Chlamydomonas reinhardtii. The gene encodes a recently characterized, small protein of the cytochrome b6f f complex, and based on this sequence, it is proposed that this protein spans the membrane by a single α-helix. Comparison of the nucleotide sequence with the deduced amino acid sequence reveals a 60-amino-acid presequence similar to a stroma-targeting peptide.
