ABO blood group

A transferase, B transferase, GTB, ABO glycosyltransferase
This gene encodes proteins related to the first discovered blood group system, ABO. Which allele is present in an individual determines the blood group. The 'O' blood group is caused by a deletion of guanine-258 near the N-terminus of the protein which results in a frameshift and translation of an almost entirely different protein. Individuals with the A, B, and AB alleles express glycosyltransferase activities that convert the H antigen into the A or B antigen. Other minor alleles have been found for this gene.

Effects of Nanoparticle Size on Multilayer Formation and Kinetics of Tethered Enzymes.
Travis et al., Ithaca, United States. In Bioconjug Chem, Oct 2015
Here, we standardize NP attachment strategy (oriented immobilization via hexahistidine tags) and composition (Ni-NTA coated gold NPs), to test the impact of NP size (⌀5, 10, 20, and 50 nm) on multilayer formation, activity, and kinetic parameters (kcat, KM, kcat/KM) of enzymes representing three different classes: glucose-6-phosphate isomerase (GPI), an isomerase; Glyceraldehyde-3-phosphate dehydrogenase S (GAPDHS), an oxidoreductase; and pyruvate kinase (PK), a transferase.
Intrinsic Levanase Activity of Bacillus subtilis 168 Levansucrase (SacB).
López Munguía et al., Ecatepec, Mexico. In Plos One, 2014
As levanase, levansucrase may use levan as substrate and, through a fructosyl-enzyme complex, behave as a hydrolytic enzyme or as a transferase, as demonstrated when glucose and fructose are added as acceptors.
Monolignol ferulate transferase introduces chemically labile linkages into the lignin backbone.
Ralph et al., East Lansing, United States. In Science, 2014
Herein, we describe the isolation of a transferase gene capable of forming these conjugates and its xylem-specific introduction into poplar.
Complementary innate (anti-A-specific) IgM emerging from ontogenic O-GalNAc-transferase depletion: (Innate IgM complementarity residing in ancestral antigen completeness).
Arend, Iowa City, United States. In Immunobiology, 2014
The structure either passes "completely" through the germline, in transferase-secreting mature tissues becoming the "complete" phenotype AB, or disappears in exhaustive glycotransferase depletion from the differentiating cell surfaces and leaves behind the "incomplete" blood group O-phenotype, which has released a transferase- and O-glycan-depleted, complementary glycoprotein (IgM) into the circulation.

3. Renal functions involved in sodium homeostasis include: (i) the rate of glomerular filtration (GFR) determined by renal haemodynamics, including tubuloglomerular feedback (TGF); (ii) proximal tubular reabsorption involving glomerulotubular balance (GTB) and neurohumoral control; (iii) macula densa mechanisms influencing TGF and renin secretion; and (iv) distal tubular reabsorption dominated by the renin-angiotensin-aldosterone system (RAAS).
