Figure 1.

Overview of the hexokinase genes in Physcomitrella. Exons are shown as gray boxes and introns as solid black lines. The predicted exon/intron organization is based on existing cDNA sequences and, if cDNA sequences were missing or aberrantly spliced, on the known splice pattern of other plant hexokinase genes, provided that the consensus donor and acceptor splice sites are conserved. The predicted transit peptides in the type A hexokinases and the membrane anchors in the type B and D hexokinases are shown as small boxes under exon 1.
