Figure 5From: Testis-specific glyceraldehyde-3-phosphate dehydrogenase: origin and evolutionK a /K s profiles. Five GAPD isoenzymes are compared: GAPD-1 and GAPD-2 of mammals, GAPD-1 and GAPD-2 of teleosts and GAPD of insects. Numbering of the X axis starts immediately after the proline-rich domain of mammalian GAPD-2 and corresponds to the positions in protein sequences.Back to article page
