Enzymes

General function:
Involved in transferase activity
Specific function:
Conversion of 1,4-dihydroxy-2-naphthoate (DHNA) to dimethylmenaquinone (DMK). Attaches octaprenylpyrophosphate, a membrane-bound 40-carbon side chain to DHNA. The conversion of DHNA to DMK proceeds in three stages:the removal of the carboxyl group of DHNA as CO(2), the attachment of the isoprenoid side chain, and a quinol-to-quinone oxidation, which is thought to be spontaneous
Gene Name:
menA
Uniprot ID:
P32166
Molecular weight:
33594
Reactions
An all-trans-polyprenyl diphosphate + 1,4-dihydroxy-2-naphthoate = a demethylmenaquinol + diphosphate + CO(2).
General function:
Involved in methyltransferase activity
Specific function:
Methyltransferase required for the conversion of dimethylmenaquinone (DMKH2) to menaquinone (MKH2) and the conversion of 2-polyprenyl-6-methoxy-1,4-benzoquinol (DDMQH2) to 2-polyprenyl-3-methyl-6-methoxy-1,4-benzoquinol (DMQH2)
Gene Name:
ubiE
Uniprot ID:
P0A887
Molecular weight:
28073
Reactions
A demethylmenaquinone + S-adenosyl-L-methionine = a menaquinol + S-adenosyl-L-homocysteine.
S-adenosyl-L-methionine + 2-methoxy-6-all-trans-polyprenyl-1,4-benzoquinol = S-adenosyl-L-homocysteine + 6-methoxy-3-methyl-2-all-trans-polyprenyl-1,4-benzoquinol.
