Protein Info for ECD_01020 in Escherichia coli BL21

Annotation: inactive ferrous ion transporter EfeUOB

These analyses and tools can help you predict a protein's function, but be skeptical. For enzymes, over 10% of annotations from KEGG or SEED are probably incorrect. For other types of proteins, the error rates may be much higher. MetaCyc and Swiss-Prot have low error rates, but the best hits in these databases are often quite distant, so this protein's function may not be the same. TIGRFam has low error rates. Finally, many experimentally-characterized proteins are not in any of these databases. To find relevant papers, use PaperBLAST.

Best Hits

Swiss-Prot: 100% identical to EFEO_SHIFL: Iron uptake system component EfeO (efeO) from Shigella flexneri

KEGG orthology group: K07224, putative lipoprotein (inferred from 100% identity to eco:b1018)

MetaCyc: 100% identical to ferrous iron transport system protein EfeO (Escherichia coli K-12 substr. MG1655)

Predicted SEED Role

"Ferrous iron transport periplasmic protein EfeO, contains peptidase-M75 domain and (frequently) cupredoxin-like domain"
