Catalysis of the reaction: UDP-N-acetylmuramoyl-L-alanyl-D-glutamyl-L-lysine + ATP + D-alanyl-D-alanine = phosphate + UDP-N-acetylmuramoyl-L-alanyl-D-glutamyl-L-lysyl-D-alanyl-D-alanine + ADP.

Comment
Note that the enzyme UDP-N-acetylmuramoyl-tripeptide-D-alanyl-D-alanine ligase also has UDP-N-acetylmuramoylalanyl-D-glutamyl-2,6-diaminopimelate-D-alanyl-D-alanine ligase activity (GO:0008766).
