Xylanolytic transcriptional activator xlnR

Gene

xlnR

Organism
Aspergillus niger
Status
Reviewed-Annotation score: Annotation score: 3 out of 5-Experimental evidence at protein leveli

Functioni

Transcriptional activator of the xylanolytic system. Involved in the regulation of extracellular cellulolytic and xylanolytic genes and in the regulation of the intracellular activities of D-xylose catabolic genes in the pentose catabolic pathway (PCP) in response to the presence of D-xylose. Binds to the DNA sequence 5'-GGNTAAA-3'.10 Publications

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.
