Functioni

Catalyzes the reversible reduction of NADP+ by F420H2. In this reaction the proS hydrogen at C5 of F420 is transferred into the proS position at C4 of NADPH.2 Publications

Catalytic activityi

Reduced coenzyme F420 + NADP+ = oxidized coenzyme F420 + NADPH.1 Publication

Kineticsi

  1. KM=20 µM for reduced coenzyme F420 (at pH 8.0 and 65 degrees Celsius)1 Publication
  2. KM=40 µM for NADP+ (at pH 8.0 and 65 degrees Celsius)1 Publication
  3. KM=10 µM for oxidized coenzyme F420 (at pH 5.5 and 65 degrees Celsius)1 Publication
  4. KM=40 µM for NADPH (at pH 5.5 and 65 degrees Celsius)1 Publication
  1. Vmax=660 µmol/min/mg enzyme for NADP reduction with F420H2 (at pH 5.5 and 80 degrees Celsius)1 Publication

pH dependencei

Optimum pH is 8.0 for NADP reduction with F420H2. Optimum pH is 5.5 for F420 reduction with NADPH.1 Publication

Temperature dependencei

Optimum temperature is 80 degrees Celsius. Is highly thermostable.1 Publication

Similar proteinsi

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
