1,3-b-galaktozil-N-acetilheksozamin fosforilaza (EC 2.4.1.211, lakto-N-biozna fosforilaza, LNBP, galakto-N-biozna fosforilaza) je enzim sa sistematskim imenom beta-D-galaktopiranozil-(1->3)-N-acetil-D-heksozamin:fosfat galaktoziltransferaza.^[1] Ovaj enzim katalizuje sledeću hemijsku reakciju

beta-D-galaktopiranozil-(1->3)-N-acetil-D-glukozamin + fosfat

\rightleftharpoons

alfa-D-galaktopiranoza 1-fosfat + N-acetil-D-glukozamin

Ova reakcija se takođe odvija sa beta-D-galaktopiranozil-(1->3)-N-acetil-D-galaktozaminom kao supstratom, pri čemu se formira N-acetil-D-galaktozamin kao produkt.
