| T1 |
0-118 |
Sentence |
denotes |
Molecular cloning and expression of a sixth type of alpha 2,8-sialyltransferase (ST8Sia VI) that sialylates O-glycans. |
| T2 |
119-273 |
Sentence |
denotes |
A novel member of the mouse alpha2,8-sialyltransferase (ST8Sia) family, designated ST8Sia VI, was identified by BLAST analysis of expressed sequence tags. |
| T3 |
274-519 |
Sentence |
denotes |
The sequence of ST8Sia VI encodes a protein of 398 amino acids and shows 42.0 and 38.3% amino acid sequence identities to mouse alpha2,8-sialyltransferases ST8Sia I (GD3 synthase) and ST8Sia V (GD1c, GT1a, GQ1b, and GT3 synthases), respectively. |
| T4 |
520-770 |
Sentence |
denotes |
The recombinant soluble form of ST8Sia VI expressed in COS-7 cells exhibited alpha2,8-sialyltransferase activity toward both glycolipids and glycoproteins that have the NeuAcalpha2,3(6)Gal sequence at the nonreducing end of their carbohydrate groups. |
| T5 |
771-871 |
Sentence |
denotes |
This enzyme formed NeuAcalpha2,8NeuAc structures, but not oligosialic or polysialic acid structures. |
| T6 |
872-998 |
Sentence |
denotes |
Analysis of the fetuin sialylated by ST8Sia VI indicated that ST8Sia VI prefers O-glycans to N-glycans as acceptor substrates. |
| T7 |
999-1129 |
Sentence |
denotes |
Substrate specificities and kinetic properties also showed that ST8Sia VI prefers O-glycans to glycolipids as acceptor substrates. |
| T8 |
1130-1350 |
Sentence |
denotes |
ST8Sia VI also exhibited activity toward oligosaccharides such as sialyllactose and sialyllactosamine, and the structure of the minimal acceptor substrate for ST8Sia VI was determined as the NeuAcalpha2,3(6)Gal sequence. |
| T9 |
1351-1508 |
Sentence |
denotes |
The expression of the ST8Sia VI gene was ubiquitous, and the highest expression was observed in kidney, with three major transcripts of 8.2, 3.8, and 2.7 kb. |
| T10 |
1509-1617 |
Sentence |
denotes |
This is the first report of a mammalian alpha2,8-sialyltransferase that sialylates O-glycans preferentially. |
