Protein

Energy-coupling factor transporter ATP-binding protein EcfA2

Gene

ecfA2

Organism
Lactobacillus brevis (strain ATCC 367 / JCM 1170)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

ATP-binding (A) component of a common energy-coupling factor (ECF) ABC-transporter complex. Unlike classic ABC transporters this ECF transporter provides the energy necessary to transport a number of different substrates.UniRule annotation
