Function

[HUTP_BACSU] Antiterminator that binds to cis-acting regulatory sequences on the mRNA in the presence of histidine, thereby suppressing transcription termination and activating the hut operon for histidine utilization.[HAMAP-Rule:MF_00779]

Publication Abstract from PubMed

HutP is an RNA-binding protein that regulates the expression of the histidine utilization (hut) operon in Bacillus subtilis, by binding to cis-acting regulatory sequences on hut mRNA. It requires L-histidine and an Mg2+ ion for binding to the specific sequence within the hut mRNA. In the present study, we show that several divalent cations can mediate the HutP-RNA interactions. The best divalent cations were Mn2+, Zn2+ and Cd2+, followed by Mg2+, Co2+ and Ni2+, while Cu2+, Yb2+ and Hg2+ were ineffective. In the HutP-RNA interactions, divalent cations cannot be replaced by monovalent cations, suggesting that a divalent metal ion is required for mediating the protein-RNA interactions. To clarify their importance, we have crystallized HutP in the presence of three different metal ions (Mg2+, Mn2+ and Ba2+), which revealed the importance of the metal ion binding site. Furthermore, these analyses clearly demonstrated how the metal ions cause the structural rearrangements that are required for the hut mRNA recognition.
