Siat

Siat is a former municipality in the district of Surselva in the Swiss canton of Graubünden. On 1 January 2014 the former municipalities of Siat, Castrisch, Ilanz, Ladir, Luven, Pitasch, Riein, Ruschein, Schnaus, Sevgein, Duvin, Pigniu and Rueun merged into the new municipality of Ilanz/Glion.

History

Siat is first mentioned about 840 as Septe. Until 1943 Siat was known as Seth.

Geography

Before the merger, Siat had a total area of 13.5 km² (5.2 sq mi). Of this area, 51.1% is used for agricultural purposes, while 33.6% is forested. Of the rest of the land, 1.9% is settled (buildings or roads) and the remainder (13.4%) is non-productive (rivers, glaciers or mountains).

The former municipality is located in the Rueun sub-district of the Surselva district. It is located on the heights above the north side of the Vorderrhein valley and does actually not reach the plain in the valley nor the river. It consists of the haufendorf village (an irregular, unplanned and quite closely packed village, built around a central square) of Siat and the alpine herding camp of Alp da Siat on the upper end of the Val da Siat. The Senda Sursilvana multiday hiking trail passes the village as it follows the northern flank of the Vorderrhein through Falera, Ladir and Siat, continuing towards Panix.

Alpha-N-acetylneuraminyl-2,3-beta-galactosyl-1,3-N-acetylgalactosaminide 6-alpha-sialyltransferase (EC 2.4.99.7, sialyltransferase, cytidine monophosphoacetylneuraminate-(alpha-N-acetylneuraminyl-2,3-beta-galactosyl-1,3)-N-acetylgalactosaminide-alpha-2,6-sialyltransferase, alpha-N-acetylneuraminyl-2,3-beta-galactosyl-1,3-N-acetyl-galactosaminide alpha-2,6-sialyltransferase, SIAT7, ST6GALNAC, (alpha-N-acetylneuraminyl-2,3-beta-galactosyl-1,3)-N-acetyl-galactosaminide 6-alpha-sialyltransferase, CMP-N-acetylneuraminate:(alpha-N-acetylneuraminyl-2,3-beta-D-galactosyl-1,3)-N-acetyl-D-galactosaminide alpha-2,6-N-acetylneuraminyl-transferase) is an enzyme with system name CMP-N-acetylneuraminate:N-acetyl-alpha-neuraminyl-(2->3)-beta-D-galactosyl-(1->3)- N-acetyl-D-galactosaminide galactosamine-6-alpha-N-acetylneuraminyltransferase. This enzyme catalyses the following chemical reaction

This enzyme attaches N-acetylneuraminic acid in alpha-2,6-linkage to N-acetyl-galactosamine only when present in the structure, where R may be protein or p-nitrophenol.
