Asymmetric/Biological Unit(hide GO term definitions)
Chain A   (YBAK_HAEIN | P45202)
molecular function
    GO:0043906    Ala-tRNA(Pro) hydrolase activity    Catalysis of the hydrolysis of misacylated Ala-tRNA(Pro).
    GO:0002161    aminoacyl-tRNA editing activity    The hydrolysis of an incorrectly aminoacylated tRNA.
    GO:0016829    lyase activity    Catalysis of the cleavage of C-C, C-O, C-N and other bonds by other means than by hydrolysis or oxidation, or conversely adding a group to a double bond. They differ from other enzymes in that two substrates are involved in one reaction direction, but only one in the other direction. When acting on the single substrate, a molecule is eliminated and this generates either a new double bond or a new ring.
biological process
    GO:0006450    regulation of translational fidelity    Any process that modulates the ability of the translational apparatus to interpret the genetic code.
    GO:0006412    translation    The cellular metabolic process in which a protein is formed, using the sequence of a mature mRNA or circRNA molecule to specify the sequence of amino acids in a polypeptide chain. Translation is mediated by the ribosome, and begins with the formation of a ternary complex between aminoacylated initiator methionine tRNA, GTP, and initiation factor 2, which subsequently associates with the small subunit of the ribosome and an mRNA or circRNA. Translation ends with the release of a polypeptide chain from the ribosome.
cellular component
    GO:0005737    cytoplasm    All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.
