Metabolite Identification
Common NameL-Methionine
DescriptionL-Methionine, also known as liquimeth or pedameth, belongs to the class of organic compounds known as methionine and derivatives. Methionine and derivatives are compounds containing methionine or a derivative thereof resulting from reaction of methionine at the amino group or the carboxy group, or from the replacement of any hydrogen of glycine by a heteroatom. L-Methionine is a drug which is used for protein synthesis including the formation of same, l-homocysteine, l-cysteine, taurine, and sulfate. L-Methionine exists as a solid, possibly soluble (in water), and a very strong basic compound (based on its pKa) molecule. L-Methionine exists in all living species, ranging from bacteria to humans. L-Methionine is a potentially toxic compound.

Enzymes

General function:
Coenzyme transport and metabolism
Specific function:
Catalyzes the formation of S-adenosylmethionine from methionine and ATP.
Gene Name:
MAT2A
Uniprot ID:
A7E3T7
Molecular weight:
43691.0
General function:
Coenzyme transport and metabolism
Specific function:
Catalyzes the radical-mediated insertion of two sulfur atoms into the C-6 and C-8 positions of the octanoyl moiety bound to the lipoyl domains of lipoate-dependent enzymes, thereby converting the octanoylated domains into lipoylated derivatives.
Gene Name:
LIAS
Uniprot ID:
Q5BIP7
Molecular weight:
42035.0
General function:
Coenzyme transport and metabolism
Specific function:
Catalyzes the formation of S-adenosylmethionine from methionine and ATP. The reaction comprises two steps that are both catalyzed by the same enzyme: formation of S-adenosylmethionine (AdoMet) and triphosphate, and subsequent hydrolysis of the triphosphate.

General function:
Amino acid transport and metabolism
Specific function:
Catalyzes the transfer of a methyl group from methyl-cobalamin to homocysteine, yielding enzyme-bound cob(I)alamin and methionine. Subsequently, remethylates the cofactor using methyltetrahydrofolate (By similarity).

Uniprot ID:
Q4JIJ3
Molecular weight:
140478.0
Reactions
Homocysteine + 5-Methyltetrahydrofolic acid → L-Methionine + Tetrahydrofolic aciddetails
General function:
Posttranslational modification, protein turnover, chaperones
Specific function:
Methionine-sulfoxide reductase that specifically reduces methionine (R)-sulfoxide back to methionine. While in many cases, methionine oxidation is the result of random oxidation following oxidative stress, methionine oxidation is also a post-translational modification that takes place on specific residue. Acts as a regulator of actin assembly by reducing methionine (R)-sulfoxide mediated by MICALs (MICAL1, MICAL2 or MICAL3) on actin, thereby promoting filament repolymerization. Plays a role in innate immunity by reducing oxidized actin, leading to actin repolymerization in macrophages.
Gene Name:
MSRB1
Uniprot ID:
Q3MHL9
Molecular weight:
12833.0
General function:
Translation, ribosomal structure and biogenesis
Specific function:
Cotranslationally removes the N-terminal methionine from nascent proteins. The N-terminal methionine is often cleaved when the second residue in the primary sequence is small and uncharged (Met-Ala-, Cys, Gly, Pro, Ser, Thr, or Val).

General function:
Amino acid transport and metabolism
Specific function:
Involved in the regulation of homocysteine metabolism. Converts betaine and homocysteine to dimethylglycine and methionine, respectively. This reaction is also required for the irreversible oxidation of choline (By similarity).

Reactions
L-Methionine + Adenosine triphosphate + tRNA(Met) → L-Methionyl-tRNA(Met) + Adenosine monophosphate + Pyrophosphatedetails
General function:
Translation, ribosomal structure and biogenesis
Specific function:
Catalyzes the specific attachment of an amino acid to its cognate tRNA in a 2 step reaction: the amino acid (AA) is first activated by ATP to form AA-AMP and then transferred to the acceptor end of the tRNA. Plays a role in the synthesis of ribosomal RNA in the nucleolus.
