B. <strong>Structure</strong>s<br />

Figure 8<br />

Sequence alignment of several members of the aldo-keto reductase family. Abbreviations used<br />

are HALR2, human aldose reductase (30); HALR1, human aldehyde reductase [30]; 3α-HSD,<br />

3α-hydroxysteroid dehydrogenase [32]; FR-1, murine FR-1 [33]; BPGFS, bovine<br />

prostaglandin F synthase [34]; CCDR12, human chlordecone reductase [31]; CDGR,<br />

Corynebacterium diketogluconate reductase [38]; MVDP, murine vas deferens protein [35],<br />

JFRC, Japanese frog ρ crystallin [36].<br />

<strong>Structure</strong>s of several other members of the aldo-keto reductase family have also been determined. These<br />

include aldehyde reductase [39,40], FR-1 [41] and 3α-hydroxysteroid dehydrogenase [42]. Since each of<br />

these proteins retain a large amount of sequence identity and homology with human ALR2, it is not<br />

surprising to note that the overall tertiary structures are very similar. Root-meansquare C α deviations<br />

between the human ALR2 holoenzyme structure and the rest of the family are in the range of 1–2Å<br />
