Synthesis of Neoglycoproteins Using Oligosaccharide-transfer Activity with Endo-β-N-Acetylglucosaminidase
TL;DR: A novel method for the enzymatic synthesis of neoglycoproteins from Arthrobacter protophormiae with high levels of transglycosylation activity is described and all of the N-linked sugar chains of the synthetic neoribonuclease of the pyridylamino derivatives were modified to (Man)6(GlcNAc)2.

Takehiro Takama,Keiichi Okano,Akihiro Kondo,Shintaro Akamoto,Masao Fujiwara,Hisashi Usuki,Yasuyuki Suzuki +6 more
TL;DR: Adjustments to the extent of surgery among oldest old patients most likely reduces the incidence of postoperative complications in this group, and preoperative serum albumin level and PNI are significant predictors of post operative complications in oldest old Patients with gastric cancer.

TL;DR: N-Acetylglucosamine at the reducing end of the latter sugar chain was found by HPLC of the carbohydrate composition and of an exoglycosidase digest of the pyridylamino derivative of the reducing-end residue, and by 400 MHz 1H-NMR spectroscopy.
