General annotation (Comments)

Function

Catalyzes the addition of both L- and D-lysine to the nucleotide precursor UDP-N-acetylmuramoyl-L-alanyl-D-glutamate (UMAG) in the biosynthesis of bacterial cell-wall peptidoglycan. Is also able to use meso-diaminopimelate as the amino acid substrate in vitro, although much less efficiently. Ref.2

Catalytic activity

ATP + UDP-N-acetylmuramoyl-L-alanyl-D-glutamate + L-lysine = ADP + phosphate + UDP-N-acetylmuramoyl-L-alanyl-D-glutamyl-L-lysine. HAMAP-Rule MF_00208

ATP + UDP-N-acetylmuramoyl-L-alanyl-D-glutamate + D-lysine = ADP + phosphate + UDP-N-acetylmuramoyl-L-alanyl-D-glutamyl-D-lysine.

Pathway

Cell wall biogenesis; peptidoglycan biosynthesis. HAMAP-Rule MF_00208

Subcellular location

Cytoplasm By similarity.

Post-translational modification

Carbamoylation is probably crucial for Mg2+ binding and, consequently, for the gamma-phosphate positioning of ATP By similarity. HAMAP-Rule MF_00208

Miscellaneous

The peptidoglycan of T.maritima was shown to contain approximate amounts of both enantiomers of lysine and no diaminopimelate. HAMAP-Rule MF_00208

Sequence similarities

Belongs to the MurCDEF family. MurE subfamily.

Biophysicochemical properties

Kinetic parameters:

The catalytic efficiency for the L-lysine adding activity is 4-fold and 10-fold higher than that for the D-lysine and meso-diaminopimelate adding activity, respectively.

KM=0.45 mM for UDP-N-acetylmuramoyl-L-Ala-D-Glu Ref.2

KM=2.8 mM for L-lysine (at pH 9.4)

KM=0.65 mM for L-lysine (at pH 8)

KM=1.7 mM for D-lysine (at pH 9.4)

KM=1.0 mM for D-lysine (at pH 8)

KM=4.8 mM for meso-diaminopimelate (at pH 9.4)

KM=27 mM for L-ornithine (at pH 9.4)

KM=3.6 mM for ATP

pH dependence:

Optimum pH is 9.4 for the L-lysine adding activity.

Temperature dependence:

Optimum temperature is 68 degrees Celsius for the L-lysine adding activity.
