Gene model for YlMDH2. (A) Schematic representation of alternative transcripts from the multi-intronic MDH gene YlMDH2. Exons are represented by grey rectangles and introns are symbolized by thin black articulated lines. Vertical bars on each of the three phases (0, +1 and +2) represent in-frame stop codons. (B) Sequence representation of the 3′ regions centred on the second intron. Coloured circles indicate the 5′-splice site, the BP and the two 3′-splice sites used to generate the two mRNA variants. Exon parts are represented by grey rectangles and the two putative C-terminal protein sequences are indicated.
