B-galaktozid a-2,6-sijaliltransferaza (EC 2.4.99.1, CMP-N-acetilneuraminat:beta-D-galaktozil-1,4-N-acetil-beta-D-glukozamin alfa-2,6-N-acetilneuraminiltransferaza) je enzim sa sistematskim imenom CMP-N-acetilneuraminat:beta-D-galaktozil-(1->4)-N-acetil-beta-D-glukozamin alfa-(2->6)-N-acetilneuraminiltransferaza.[1][2][3][4][5] Ovaj enzim katalizuje sledeću hemijsku reakciju
- CMP-N-acetilneuraminat + beta-D-galaktozil-(1->4)-N-acetil-beta-D-glukozamin CMP + alfa-N-acetilneuraminil-(2->6)-beta-D-galaktozil-(1->4)-N-acetil-beta-D-glukozamin
Terminalni beta-D-galaktozilni ostatak oligosaharida glikoproteina, kao i laktoza, mogu da deluju kao akceptori.
