Lipid II:glicin gliciltransferaza (EC 2.3.2.16, N-acetilmuramoil-L-alanil-D-glutamil-L-lizil-D-alanil-D-alanin-difosfoundekaprenil-N-acetilglukozamin:N⁶-glicin transferaza, femX (gen)) je enzim sa sistematskim imenom alanil-D-alanin-difosfo-ditrans,oktacis-undekaprenil-N-acetilglukozamin:glicin N⁶-gliciltransferaza.^[1] Ovaj enzim katalizuje sledeću hemijsku reakciju

N-acetilmuramoil-L-alanil-D-izoglutaminil-L-lizil-D-alanil-D-alanin-difosfo-ditrans,oktacis-undekaprenil-N-acetilglukozamin + glicil-tRNK

\rightleftharpoons

N-acetilmuramoil-L-alanil-D-izoglutaminil-L-lizil-(N⁶-glicil)-D-alanil-D-alanin-difosfo-ditrans,oktacis-undekaprenil-N-acetilglukozamin + tRNK

Enzim iz Staphylococcus aureus katalizuje transfer glicina sa naelektrisane tRNK na N-acetilmuramoil-L-alanil-D-izoglutaminil-L-lizil-D-alanil-D-alanin-difosfoundekaprenil-N-acetilglukozamin (lipid II), vezujući ga na N⁶ L-lizina u poziciji 3 pentapeptida.
