Chain A (RNSA_STRAU | P05798)

molecular function
	GO:0003723	RNA binding	Interacting selectively and non-covalently with an RNA molecule or a portion thereof.
	GO:0004519	endonuclease activity	Catalysis of the hydrolysis of ester linkages within nucleic acids by creating internal breaks.
	GO:0004521	endoribonuclease activity	Catalysis of the hydrolysis of ester linkages within ribonucleic acid by creating internal breaks.
	GO:0016787	hydrolase activity	Catalysis of the hydrolysis of various bonds, e.g. C-O, C-N, C-C, phosphoric anhydride bonds, etc. Hydrolase is the systematic name for any enzyme of EC class 3.
	GO:0004518	nuclease activity	Catalysis of the hydrolysis of ester linkages within nucleic acids.
	GO:0046589	ribonuclease T1 activity	Catalysis of the endonucleolytic cleavage to nucleoside 3'-phosphates and 3'-phosphooligonucleotides ending in Gp with 2',3'-cyclic phosphate intermediates.
	GO:0004540	ribonuclease activity	Catalysis of the hydrolysis of phosphodiester bonds in chains of RNA.
biological process
	GO:0090501	RNA phosphodiester bond hydrolysis	The RNA metabolic process in which the phosphodiester bonds between ribonucleotides are cleaved by hydrolysis.
	GO:0090502	RNA phosphodiester bond hydrolysis, endonucleolytic	The chemical reactions and pathways involving the hydrolysis of internal 3',5'-phosphodiester bonds in one or two strands of ribonucleotides.

cellular component
	GO:0005576	extracellular region	The space external to the outermost structure of a cell. For cells without external protective or external encapsulating structures this refers to space outside of the plasma membrane. This term covers the host cell environment outside an intracellular parasite.

Chain B (BARS_BACAM | P11540)

cellular component
	GO:0005737		cytoplasm		All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.
