Gene Ontology annotation through association of InterPro records with GO terms
Gene Ontology annotation based on UniProtKB/Swiss-Prot keyword mapping
-
Maps UniProtKB keywords to broad GO terms
-
Source of redundant general terms (hydrolase, metal ion binding, ion transport)
Electronic GO annotations transferred based on shared sequence features
Automatic assignment of GO terms using logical inference
Combined Automated Annotation using Multiple IEA Methods
-
Combines InterPro, UniRule, and keyword-based annotations
-
Primary source for most IEA annotations on this protein
Deep research on KdpB function based on literature review
-
KdpB is the catalytic P-type ATPase subunit of the KdpFABC high-affinity K+ uptake system
"kdpB encodes the catalytic P-type ATPase subunit of the KdpFABC high-affinity K+ uptake system"
-
K+ is selected in KdpA selectivity filter and delivered to KdpB via a 40 A tunnel
"K+ is selected in KdpA's channel-like selectivity filter and delivered to the KdpB transmembrane ion-binding site via a ~40 A tunnel"
-
The functional complex resides in the inner membrane
"The functional complex resides in the inner membrane and requires KdpA/B/C plus the small stabilizer KdpF"
