    Summary
    This carbohydrate-specific porin preferentially binds arbutin, salicin and cellobiose. bglH is part of the cryptic bglGFBH operon. [More information is available at EcoGene: EG11364]. BghL is an outer-membrane porin coded for by a gene in the cryptic bgl operon. [More information is available at EcoCyc: EG11364].
