The MurE synthetase from Thermotoga maritima is endowed with an unusual D-lysine adding activity.
Boniface A., Bouhss A., Mengin-Lecreulx D., Blanot D.
The peptidoglycan of Thermotoga maritima, an extremely thermophilic eubacterium, was shown to contain no diaminopimelic acid and approximate amounts of both enantiomers of lysine (Huber, R., Langworthy, T. A., König, H., Thomm, M., Woese, C. R., Sleytr, U. B., and Stetter, K. O. (1986) Arch. Micro ... >> More
The peptidoglycan of Thermotoga maritima, an extremely thermophilic eubacterium, was shown to contain no diaminopimelic acid and approximate amounts of both enantiomers of lysine (Huber, R., Langworthy, T. A., König, H., Thomm, M., Woese, C. R., Sleytr, U. B., and Stetter, K. O. (1986) Arch. Microbiol. 144, 324-333). To assess the possible involvement of the MurE activity in the incorporation of D-lysine, the murE gene from this organism was cloned in Escherichia coli, and the corresponding protein was purified as the C-terminal His6-tagged form. In vitro assays showed that D-lysine and meso-diaminopimelic acid were added to UDP-N-acetylmuramoyl-dipeptide with 25 and 10% efficiencies, respectively, relative to L-lysine. The purified enzyme was used to synthesize the L- and D-lysine-containing UDP-N-acetylmuramoyl-tripeptides; chemical analysis revealed an unusual structure for the D-lysine-containing nucleotide, namely acylation of the epsilon-amino function of D-lysine by the D-glutamyl residue. In vitro assays with MurF and MraY enzymes from T. maritima showed that this novel nucleotide was not a substrate for MurF but that it could be directly processed into tripeptide lipid I by MraY, thereby substantiating the role of MurE in the incorporation of D-lysine into peptidoglycan. << Less
