Notes

[back to top]

First 24 aa are a predicted type II signal peptide. YjfO is the only one of ten YhcN paralogs that is predicted to have a type II signal peptide; the others have type I signals predicted or verified.^[4]

BsmA (YjfO) is a member of the YhcN_Family of paralogs.^[5]

Notes

1 Jun 2009: The amino acid sequence was updated to match EcoCyc release 13.0 and EcoGene. The MW, pI, and extinction coefficient calculated for the preprotein and the mature protein. The N-terminus was redefined based on sequence similarity to the other YhcN paralogs. ^[5]
