== Function == | |||
[https://www.uniprot.org/uniprot/EGTUB_STRP2 EGTUB_STRP2] Part of an ABC transporter complex EgtU required for the uptake of ergothioneine (EGT), a natural low-molecular weight (LMW) thiol antioxidant (PubMed:36481738). Responsible for the translocation of the substrate across the membrane (PubMed:36481738). Also contains a C-terminal periplasmic solute-binding domain (SBD) which binds to EGT with sub-micromolar affinity (PubMed:36481738). Binds L-hercynine about 10,000-fold less tightly than EGT (PubMed:36481738). Cannot bind the structurally similar compounds L-histidine, proline-betaine, choline, ectoine, carnitine or dimethylpropiothetin (PubMed:36481738).<ref>PMID:36481738</ref> | |||
