L-proline cis-3-hydroxylase 2

Gene
N/A
Organism
Streptomyces sp.
Status
Reviewed-Annotation score: Annotation score: 4 out of 5-Experimental evidence at protein leveli

Functioni

Dioxygenase that catalyzes the 2-oxoglutarate-dependent selective hydroxylation of free L-proline to cis-3-hydroxy-L-proline (cis-3-Hyp).1 Publication

Catalytic activityi

L-proline + 2-oxoglutarate + O2 = cis-3-hydroxy-L-proline + succinate + CO2.1 Publication

Cofactori

Fe2+1 PublicationNote: Binds 1 Fe2+ ion.1 Publication

Enzyme regulationi

Inhibited by metal ions such as Co2+, Zn2+, Ni2+ or Cu2+. Is also inhibited by EDTA in vitro.1 Publication

Kineticsi

Comparison of both proline 3-hydroxylase isozymes shows that type II enzyme has 1.8-fold higher activity than type I upon L-proline, and 24-fold higher activity upon L-2-azetidinecarboxylic acid.

    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.
