RPSBLAST alignment for GI: 254780870 and conserved domain: cd00778

>gnl|CDD|29823 cd00778, ProRS_core_arch_euk, Prolyl-tRNA synthetase (ProRS) class II core catalytic domain. ProRS is a homodimer. It is responsible for the attachment of proline to the 3' OH group of ribose of the appropriate tRNA. This domain is primarily responsible for ATP-dependent formation of the enzyme bound aminoacyl-adenylate. Class II assignment is based upon its structure and the presence of three characteristic sequence motifs in the core domain. This subfamily contains the core domain of ProRS from archaea, the cytoplasm of eukaryotes and some bacteria.. Length = 261
