124330-54-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 124330-54-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,4,3,3 and 0 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 124330-54:
(8*1)+(7*2)+(6*4)+(5*3)+(4*3)+(3*0)+(2*5)+(1*4)=87
87 % 10 = 7
So 124330-54-7 is a valid CAS Registry Number.

Pseudoglycosyltransferase catalyzes nonglycosidic C-N coupling in validamycin a biosynthesis

Asamizu, Shumpei,Yang, Jongtae,Almabruk, Khaled H.,Mahmud, Taifo

scheme or table, p. 12124 - 12135 (2011/10/09)

Glycosyltransferases are ubiquitous in nature. They catalyze a glycosidic bond formation between sugar donors and sugar or nonsugar acceptors to produce oligo/polysaccharides, glycoproteins, glycolipids, glycosylated natural products, and other sugar-containing entities. However, a trehalose 6-phosphate synthase-like protein has been found to catalyze an unprecedented nonglycosidic C-N bond formation in the biosynthesis of the aminocyclitol antibiotic validamycin A. This dedicated 'pseudoglycosyltransferase catalyzes a condensation between GDP-valienol and validamine 7-phosphate to give validoxylamine A 7′-phosphate with net retention of the 'anomeric configuration of the donor cyclitol in the product. The enzyme operates in sequence with a phosphatase, which dephosphorylates validoxylamine A 7′-phosphate to validoxylamine A.
