Asymmetric Unit(hide GO term definitions)

Chain A (Q8XZN3_RALSO | Q8XZN3)

molecular function
	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:0019120	hydrolase activity, acting on acid halide bonds, in C-halide compounds	Catalysis of the hydrolysis of any acid halide bond in substances containing halogen atoms in organic linkage.
biological process
	GO:0008152	metabolic process	The chemical reactions and pathways, including anabolism and catabolism, by which living organisms transform chemical substances. Metabolic processes typically transform small molecules, but also include macromolecular processes such as DNA repair and replication, and protein synthesis and degradation.
