Structure of the Chlamydomonas reinhardtii cabII-1 gene encoding a chlorophyll-a/b-binding protein.

Gene cabII-1 is a light regulated gene that encodes the precursor of a major chlorophyll-a/b-binding protein in Chlamydomonas reinhardtii. It is a member of a small gene family composed of about 3-7 members. Nucleotide sequencing data and S1 mapping reveal that the cabII-1 gene is interrupted by three introns. Except for the transit peptide and the N-terminus, the cabII-1 gene product is similar to cabII proteins in higher plants. The cabII-1 gene in C. reinhardtii appears to be an intermediate between type-I and type-II cabII genes described in higher plants.
