Ohio Graduation Test. The Ohio Graduation Test (OGT) is the high school graduation examination given to sophomores in the U.S. state of Ohio. Students must pass all five sections (reading, writing, mathematics, science and social studies) in order to graduate. Students have multiple chances to pass these sections and can still graduate without ...
O-GlcNAc (short for O-linked GlcNAc or O-linked β-N-acetylglucosamine) is a reversible enzymatic post-translational modification that is found on serine and threonine residues of nucleo cytoplasmic proteins. The modification is characterized by a β-glycosidic bond between the hydroxyl group of serine or threonine side chains and N ...
OGT cleaves Host Cell Factor C1, at one or more of 6 repeating 26 amino acid sequences. The TPR domain of OGT binds to the carboxyl terminal portion of an HCF1 proteolytic repeat so that the cleavage region is in the glycosyltransferase active site above uridine-diphosphate-GlcNAc [11] The large proportion of OGT complexed with HCF1 is necessary for HCF1 cleavage, and HCFC1 is required for OGT ...
Two conserved enzymes control this glycosylation of serine and threonine: O-GlcNAc transferase (OGT) and O-GlcNAcase (OGA). While OGT catalyzes the addition of O-GlcNAc to serine and threonine, OGA catalyzes the hydrolytic cleavage of O-GlcNAc from post-transitionally modified proteins. [14] OGA is a member of the family of hexosaminidases ...

The glucose tolerance test was first described in 1923 by Jerome W. Conn. [4]The test was based on the previous work in 1913 by A. T. B. Jacobson in determining that carbohydrate ingestion results in blood glucose fluctuations, [5] and the premise (named the Staub-Traugott Phenomenon after its first observers H. Staub in 1921 and K. Traugott in 1922) that a normal patient fed glucose will ...
The prostate is a small gland about the size of a walnut. It’s part of the male reproductive system and sits between the penis and the bladder. The primary function of the prostate is to produce ...
AGT II shows a greater preference for O4 -alkyl thymine than O6 -alkyl guanine and alkyl phosphotriester. [1] [2] Unlike Ada, AGT II is expressed constitutively in cells. [1] [3] Therefore, AGT II will repair alkylated DNA adducts even before Ada is fully induced. AGT II is similar to Ada in its suicide inactivation in that AGT II transfers the ...
