Chain A   (LCMT1_HUMAN | Q9UIC8)
molecular function
    GO:0008757    S-adenosylmethionine-dependent methyltransferase activity    Catalysis of the transfer of a methyl group from S-adenosyl-L-methionine to a substrate.
    GO:0008168    methyltransferase activity    Catalysis of the transfer of a methyl group to an acceptor molecule.
    GO:0003880    protein C-terminal carboxyl O-methyltransferase activity    Catalysis of the transfer of a methyl group to the oxygen atom of a carboxyl group at the C-terminal of a protein.
    GO:0018423    protein C-terminal leucine carboxyl O-methyltransferase activity    Catalysis of the reaction: S-adenosyl-L-methionine + protein L-leucine = S-adenosyl-L-homocysteine + protein L-leucine methyl ester. This modification occurs only at the oxygen atoms of the free alpha carboxyl group of a leucine residue at the C-terminus of the protein.
    GO:0005515    protein binding    Interacting selectively and non-covalently with any protein or protein complex (a complex of two or more proteins that may include other nonprotein molecules).
    GO:0008276    protein methyltransferase activity    Catalysis of the transfer of a methyl group (CH3-) to a protein.
    GO:0016740    transferase activity    Catalysis of the transfer of a group, e.g. a methyl group, glycosyl group, acyl group, phosphorus-containing, or other groups, from one compound (generally regarded as the donor) to another compound (generally regarded as the acceptor). Transferase is the systematic name for any enzyme of EC class 2.
biological process
    GO:0006481    C-terminal protein methylation    The methylation of the C-terminal amino acid of a protein.
    GO:0006464    cellular protein modification process    The covalent alteration of one or more amino acids occurring in proteins, peptides and nascent polypeptides (co-translational, post-translational modifications) occurring at the level of an individual cell. Includes the modification of charged tRNAs that are destined to occur in a protein (pre-translation modification).
    GO:0032259    methylation    The process in which a methyl group is covalently attached to a molecule.
    GO:0031333    negative regulation of protein complex assembly    Any process that stops, prevents, or reduces the frequency, rate or extent of protein complex assembly.
    GO:0006479    protein methylation    The addition of a methyl group to a protein amino acid. A methyl group is derived from methane by the removal of a hydrogen atom.
    GO:0042981    regulation of apoptotic process    Any process that modulates the occurrence or rate of cell death by apoptotic process.
    GO:0010906    regulation of glucose metabolic process    Any process that modulates the rate, frequency or extent of glucose metabolism. Glucose metabolic processes are the chemical reactions and pathways involving glucose, the aldohexose gluco-hexose.
    GO:0090266    regulation of mitotic cell cycle spindle assembly checkpoint    Any process that modulates the rate, frequency, or extent of the mitotic cell cycle spindle assembly checkpoint, a cell cycle checkpoint that delays the metaphase/anaphase transition of a mitotic nuclear division until the spindle is correctly assembled and chromosomes are attached to the spindle.
cellular component
    GO:0005829    cytosol    The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes.
