Lineage
Bacteria; Pseudomonadati; Pseudomonadota; Gammaproteobacteria; Enterobacterales; Enterobacteriaceae; Escherichia
Also known as
ECK3530
Summary
Escherichia coli does not normally use exogeneous heme, but heme can be utilized if a foreign OM heme receptor is expressed in Escherichia coli (Letoffe, 2006). [More information is available at EcoGene: EG12625]. DppB is an integral membrane component of the dipeptide ABC transporter. [More information is available at EcoCyc: EG12625].
