Gene
gar1
Protein
D-galacturonate reductase
Organism
Hypocrea jecorina
Length
309 amino acids
Function
Mediates the reduction of D-galacturonate to L-galactonate, the first step in D-galacturonate catabolic process. Also has activity with D-glucuronate and DL-glyceraldehyde. No activity is observed with D-glucose, D-fructose, D-xylose, D-galactose, L-arabinose or D-mannose. Activity is seen only with NADPH and not with NADH.
Similarity
Belongs to the aldo/keto reductase family.

Protein
H/ACA ribonucleoprotein complex subunit 1
Organism
Mus musculus
Length
231 amino acids
Function
Required for ribosome biogenesis and telomere maintenance. Part of the H/ACA small nucleolar ribonucleoprotein (H/ACA snoRNP) complex, which catalyzes pseudouridylation of rRNA. This involves the isomerization of uridine such that the ribose is subsequently attached to C5, instead of the normal N1. Each rRNA can contain up to 100 pseudouridine (psi) residues, which may serve to stabilize the conformation of rRNAs. May also be required for correct processing or intranuclear trafficking of TERC, the RNA component of the telomerase reverse transcriptase (TERT) holoenzyme (By similarity).
Similarity
Belongs to the GAR1 family.
