Shikimate dehydrogenase-like protein HI_0607

Gene

sdhL

Organism
Haemophilus influenzae (strain ATCC 51907 / DSM 11121 / KW20 / Rd)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

In vitro, is able to catalyze the NADP+-dependent oxidation of shikimate to 3-dehydroshikimate. However, has much lower activity than classical shikimate dehydrogenases AroE, indicating that shikimate may not be the biological substrate. Cannot utilize NAD+ instead of NADP+. Is not able to catalyze the oxidation of quinate.1 Publication

Catalytic activityi

Shikimate + NADP+ = 3-dehydroshikimate + NADPH.1 Publication

Kineticsi

kcat is 0.2 sec(-1).1 Publication

  2. KM=234 µM for NADP+1 Publication

    pH dependencei
