RT   bgl operon and evidence for a new beta-glycohydrolase family including

CC   -!- FUNCTION: Mediates the positive regulation of the beta-glucoside (arb)
CC       operon by functioning as a transcriptional antiterminator. This is an
CC       RNA-binding protein that recognizes a specific sequence located just
CC       upstream of two termination sites within the operon (By similarity).
CC       {ECO:0000250}.
CC   -!- PTM: Phosphorylated and inactivated by ArbF (EII-Bgl). The degree of
CC       phosphorylation is dependent on the presence or absence of beta-
CC       glucosides which act as inducers of the operon expression. Addition of
CC       inducer result in the rapid dephosphorylation of ArbG (By similarity).
CC       {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the transcriptional antiterminator BglG family.
CC       {ECO:0000305}.
