== Function ==
 +
[https://www.uniprot.org/uniprot/FEMX_WEIVI FEMX_WEIVI] Involved in the synthesis of the bacterial cell wall. Catalyzes the addition of alanine into the interchain peptide bridge of peptidoglycan precursor using aminoacyl-tRNA(Ala) as amino acid donor. This alanine is added to the epsilon-amino group of the L-lysine of the peptidoglycan UDP-N-acetyl-alpha-D-muramoyl-L-alanyl-D-glutamyl-L-lysyl-D-alanyl-D-alanine, in a ribosome-independent mechanism (PubMed:11083873, PubMed:12679335, PubMed:15901708, PubMed:23744707, PubMed:4248527). Specific for UDP-N-acetyl-muramoyl-pentapeptide. Has no activity toward UDP-N-acetyl-muramoyl-tetrapeptide or UDP-N-acetyl-muramoyl-tripeptide (PubMed:15901708). Also acts on L-seryl-tRNA(Ser) (PubMed:4248527).<ref>PMID:11083873</ref> <ref>PMID:12679335</ref> <ref>PMID:15901708</ref> <ref>PMID:23744707</ref> <ref>PMID:4248527</ref>

== Publication Abstract from PubMed ==
 +
To gain insight into the catalytic mechanism of non-ribosomal amino acid transferases, peptidyl-RNA conjugates were synthesized for co-crystallization with FemXWv of Weissella viridescens, which transfers L-Ala from Ala-tRNAAla to the peptidoglycan precursor UDP-MurNAc-pentapeptide. The structure of the resulting complex and mutational studies revealed the mechanism by which FemXWv binds its substrates for substrate-assisted catalysis and stabilization of the tetrahedral intermediate.
