RPSBLAST alignment for GI: 254780445 and conserved domain: cd00672

>gnl|CDD|173899 cd00672, CysRS_core, catalytic core domain of cysteinyl tRNA synthetase. Cysteinyl tRNA synthetase (CysRS) catalytic core domain. This class I enzyme is a monomer which aminoacylates 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 = 213
 Score = 46.8 bits (112), Expect = 3e-05
 Identities = 14/36 (38%), Positives = 22/36 (61%)
