RPSBLAST alignment for GI: 254780573 and conserved domain: cd00802

>gnl|CDD|173901 cd00802, class_I_aaRS_core, catalytic core domain of class I amino acyl-tRNA synthetase. Class I amino acyl-tRNA synthetase (aaRS) catalytic core domain. These enzymes are mostly monomers which aminoacylate the 2'-OH of the nucleotide at the 3' of the appropriate tRNA. The core domain is based on the Rossman fold and is responsible for the ATP-dependent formation of the enzyme bound aminoacyl-adenylate. It contains the characteristic class I HIGH and KMSKS motifs, which are involved in ATP binding. Length = 143
 Score = 47.9 bits (114), Expect = 7e-06
 Identities = 15/56 (26%), Positives = 23/56 (41%), Gaps = 2/56 (3%)
