lactosylceramide alpha-2,3-sialyltransferase activity

Details: 
Catalysis of the reaction: cytolipin-H + CMP-N-acetylneuraminate = alpha-N-acetylneuraminyl-2,3-beta-D-galactosyl-1,4-beta-D-glucosylceramide + CMP. Alpha-N-acetylneuraminyl-2,3-beta-D-galactosyl-1,4-beta-D-glucosylceramide is also known as GM3. [EC:2.4.99.9, MetaCyc:2.4.99.9-RXN]
