High impact information on B3GALNT1

• In addition, toxin bound to P1 antigen present in group B human erythrocyte glycolipid extracts [7].
• The presence of P1 fimbriae and alpha-galactosyl residues and the absence of mannose-specific fimbriae distinguish these organisms from gut flora [1].

• Two binding sites for the NagC repressor are located at -200 and -47 bp upstream of P1 [9].

Chemical compound and disease context of B3GALNT1

• Whole egg white from pigeon, dove, and cockatiel eggs, as well as the ovomucoid fraction of pigeon egg white, exhibited strong P1 antigenic activities and inhibited agglutination of human P1 erythrocytes and of digalactoside-coated latex beads by P-fimbriated Escherichia coli strains [11].
• The disaccharide was found with peptidoglycan from all R. viridis strains investigated, as well as with R. sulfoviridis P1 and R. palustris strains, but not with peptidoglycan from R. gelatinosa, Rhodospirillum tenue, and Pseudomonas diminuta NCTC 8545 [12].
• The proteins P1, P2, and P4 of the glycine cleavage system have been purified from the anaerobic, glycine-utilizing bacterium Eubacterium acidaminophilum [13].
• The metabolism of trimethylamine (TMA) and dimethylamine (DMA) in Arthrobacter P1 involved the enzymes TMA monooxygenase and trimethylamine-N-oxide (TMA-NO) demethylase, and DMA monooxygenase, respectively [14].

Biological context of B3GALNT1

• We conclude that crucial mutations in the globoside synthase gene cause the P(k) phenotype [15].
• Surprisingly, the cDNA clones turned out to be identical with previously reported beta3Gal-T3, which had been cloned by sequence homology with other galactosyltransferases [16].
• The biochemistry and molecular genetics underlying the related carbohydrate blood group antigens P, P(k), and LKE in the GLOB collection and P1 in the P blood group system are complex and not fully understood [15].
• Substitution of adenine by 2-amino purine (2-AP) at the invariable A small middle dotT base pair at the -11 position of P1 and P3 prevented unpairing not only at that position but also at the other downstream positions, suggesting a "master" role of the adenine base at -11 of the template strand in overall base unpairing [17].
• After potassium permanganate sensitivity of unpaired thymine residues, we studied base unpairing at the -10 region during isomerization upon RNA polymerase binding at the P1 and P3 promoters of the gal operon [17].

Anatomical context of B3GALNT1

• The globoside synthase gene was expressed in many tissues, such as heart, brain, testis, etc [16].
• It appears that in adipocytes, P1 3-kinase prevents activation of GAP [18].
• Preincubation of human granules with calcium, a treatment which totally inactivates the hemolytic and cytotoxic activity of murine lymphocyte granules [perforin 1 (P1)] had no effect on human LAK granule cytotoxicity for nucleated cells [19].
• In addition, Northern blot analysis of polyadenylated RNA isolated from human LAK cells using a murine P1 complementary DNA probe showed a cross-hybridizing 2.8- to 3.0-kilobase mRNA species identical in size to murine P1 mRNA [19].
• A series of new azapeptide p-nitrophenyl esters containing a variety of P1 aza-amino acid residues have been synthesized, and the reaction of these azapeptides with chymotrypsin A alpha, subtilisin BPN', subtilisin Carlsberg, and human leukocyte cathepsin G at pH 4-7 has been studied [20].

Associations of B3GALNT1 with chemical compounds

• Hydrophobic DNA adducts were evident only in smokers, and chromatographic profiles of the adducts were similar using either the butanol extraction or nuclease P1 enhancement method, which suggested that the adducts may be derived from polycyclic aromatic hydrocarbons but not aromatic amines [21].
• No promoter hypermethylation was observed at the glutathione S-transferase P1 gene promoter [22].
• Erythrocytes from P1 individuals are shown to contain more globotriaosylceramide and less lactosylceramide than do erythrocytes from P2 individuals [23].
• In addition, the P1 carbonyl of the ketone inhibitor is pointing into the oxyanion hole and forms a hydrogen bond with the peptidic nitrogen of Gly-122, resulting in a different state compared with the tetrahedral intermediate observed in the structure of ICE and CPP32 in complex with an aldehyde inhibitor [24].
• Sequence data showed that the cDNAs contained identical 3' ends (1469 base pairs in length) to each other and to that of the human phenol transferase cDNA, HLUG P1 (Harding, D., Fournel-Gigleux, S., Jackson, M. R., and Burchell, B. (1988) Proc. Natl. Acad. Sci. U.S.A. 85, 8381-8385) [25].

Other interactions of B3GALNT1

• Northern analysis of mRNA from human organs with the four homologous cDNA revealed different expression patterns. beta3Gal-T1 mRNA was expressed in brain, beta3Gal-T2 was expressed in brain and heart, and beta3Gal-T3 and -T4 were more widely expressed [26].
• In addition, this assay was shown to be specific, because neither Stx1 nor Stx2 bound to GM3, but both bound weakly to Gb4Cer [27].

Analytical, diagnostic and therapeutic context of B3GALNT1

• By partial sequence analysis, this protein was identified as the 60 kDa human heat-shock protein (hsp) that is the P1 mitochondrial protein, and which is 50% homologous to the mycobacterial 65 kDa hsp [28].
• Human LAK granules appear to contain P1 detected as cross-reactive antigen detected by mouse anti-P1 and human anti-C9 in Western blot analysis [19].
• Calorimetric and circular dichroism methods showed that none of the P1 substitutions, except the P1-Val mutant, lead to destabilisation of the binding loop conformation [29].
• Rabbit antipeptide antisera were tested for their reactivities with the immunizing peptides and P1 protein by ELISA and immunoblots [5].
• Treatment of the enzymatic and synthetic bisphosphate adduct with nuclease P1 yielded a product that eluted at the same time from the HPLC (32P-dpG-ABZ) [30].
