== Function == | |||
[https://www.uniprot.org/uniprot/ERA_STAA8 ERA_STAA8] An essential GTPase that binds both GDP and GTP, with rapid nucleotide exchange. Plays a role in 16S rRNA processing and 30S ribosomal subunit biogenesis and possibly also in cell cycle regulation and energy metabolism.[HAMAP-Rule:MF_00367] | |||

== Publication Abstract from PubMed == | |||
GTPase Era from Staphylococcus aureus belongs to the TRAFAC superfamily of the TrmE-Era-EngA-EngB-Septin-like GTPases class and plays a significant role in the vital activity of this pathogenic microorganism as a maturation factor of the 30S ribosome subunit. However, the functions of this protein are not fully understood, making it a promising object for further study. Here, the 2.76 A resolution crystal structure of Staphylococcus aureus Era in complex with GDP is presented. Structural comparison with other GTP-bound and GDP-bound homologous proteins, GTPase domain and the KH domain revealed a mutual orientation in S. aureus which has not been described before. The GDP-bound Era structure presented here will facilitate efforts to elucidate its interactions with its regulators and lay the foundation for a structure-based search for specific inhibitors. | |||
