GeneRIFs: Gene References Into Functions

What's a GeneRIF?
  1. Role for CcmAB is suggested in the handling of heme by CcmE, which is chemically complex and involves an unusual histidine-heme covalent bond.
    Title: Loss of ATP hydrolysis activity by CcmAB results in loss of c-type cytochrome synthesis and incomplete processing of CcmE.
  2. Expression of CcmA facilitates formation of the CcmA2B1C1 complex and ATP-dependent release of holoCcmE.
    Title: ABC transporter-mediated release of a haem chaperone allows cytochrome c biogenesis.
