2.A.7.15.2
The Golgi transporter, SQV-7. Transports UDP-glucuronic acid, UDP-N-acetylgalactosamine, and UDP-galactose (Gal). These nucleotide sugars are competitive, alternate, noncooperative substrates. Mutant sqv-7 missense alleles result in severe reductions of these three transport activities. SQV-7 did not transport CMP-sialic acid, GDP-fucose, UDP-N-acetylglucosamine, UDP-glucose, or GDP-mannose (Berninsone et al. 2001).
