Crystal structure of E. coli DEAD-box protein SrmB bound to regulator of ribonuclease activity A (RraA)
Template:ABSTRACT PUBMED 24045937
Function
[D8AM26_ECOLX] Globally modulates RNA abundance by binding to RNase E (Rne) and regulating its endonucleolytic activity. Can modulate Rne action in a substrate-dependent manner by altering the composition of the degradosome. Modulates RNA-binding and helicase activities of the degradosome (By similarity).[HAMAP-Rule:MF_00471][SAAS:SAAS005493_004_044335] [SRMB_ECOLI] DEAD-box RNA helicase involved in the assembly of the 50S ribosomal subunit at low temperature. Exhibits RNA-stimulated ATP hydrolysis and RNA unwinding activity. Acts before DeaD.[1] [2] [3]
About this Structure
2yjt is a 4 chain structure with sequence from Escherichia coli k-12. Full crystallographic information is available from OCA.
