Protein Info for NIAGMN_18900 in Escherichia coli ECRC102

Name: ratA
Annotation: type II toxin-antitoxin system toxin RatA

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.

Protein Families and Features

1 50 100 149 PF10604: Polyketide_cyc2" amino acids 5 to 138 (134 residues), 43.8 bits, see alignment E=3.2e-15 PF03364: Polyketide_cyc" amino acids 14 to 139 (126 residues), 133 bits, see alignment E=7.8e-43

Best Hits

Swiss-Prot: 99% identical to RATA_SHIFL: Ribosome association toxin RatA (ratA) from Shigella flexneri
