Functioni

Catalyzes a reversible aldol reaction between acetaldehyde and D-glyceraldehyde 3-phosphate to generate 2-deoxy-D-ribose 5-phosphate.1 Publication

Catalytic activityi

2-deoxy-D-ribose 5-phosphate = D-glyceraldehyde 3-phosphate + acetaldehyde.1 Publication

Kineticsi

  1. KM=0.057 mM for 2-deoxy-D-ribose 5-phosphate1 Publication

    pH dependencei

    Optimum pH is 6.5. Is extremely stable over a wide pH range: upon heating at 50 degrees Celsius for 60 minutes, the enzyme does not lose activity at pH 4.5-11.0.1 Publication

    Temperature dependencei

    Extremely thermostable. Retains full activity upon heating at 100 degrees Celsius for 10 minutes and at 80 degrees Celsius for 60 minutes.1 Publication

    Pathwayi: 2-deoxy-D-ribose 1-phosphate degradation

    This protein is involved in step 2 of the subpathway that synthesizes D-glyceraldehyde 3-phosphate and acetaldehyde from 2-deoxy-alpha-D-ribose 1-phosphate.
    Proteins known to be involved in the 2 steps of the subpathway in this organism are:
    1. no protein annotated in this organism
    2. Deoxyribose-phosphate aldolase (deoC)
    This subpathway is part of the pathway 2-deoxy-D-ribose 1-phosphate degradation, which is itself part of Carbohydrate degradation.
    View all proteins of this organism that are known to be involved in the subpathway that synthesizes D-glyceraldehyde 3-phosphate and acetaldehyde from 2-deoxy-alpha-D-ribose 1-phosphate, the pathway 2-deoxy-D-ribose 1-phosphate degradation and in Carbohydrate degradation.
