  • Title: Structural features of a gene encoding the vacuolar H+-ATPase c subunit from a marine red alga, Porphyra yezoensis.
    Author: Kitade Y, Yamazaki S, Watanabe T, Saga N.
    Journal: DNA Res; 1999 Oct 29; 6(5):307-12. PubMed ID: 10574457.
    Abstract:
    We report the nucleotide sequence of a gene encoding the c ('16 kDa') subunit of the vacuolar-type H+-ATPase (V-ATPase) from a marine red alga, Porphyra yezoensis. A cDNA clone was isolated from a leafy gametophyte cDNA library and analyzed for the sequence. The genomic DNA sequence was directly determined by nested PCR. The structural gene contained four introns within a coding sequence of 483 base pairs which encodes a polypeptide of 161-amino acids with four hydrophobic transmembrane-spanning regions. Comparison of the deduced amino acid sequences showed higher similarity to the land plant Oryza sativa (69.1%) than to the Ulvophyceae Acetabularia acetabulum (64.1%). The mRNA was detected both in the leafy gametophytes and filamentous sporophytes.
