• Evidence is presented here that effective nucleation is possible at both ends of the collagen-like peptide (Gly-Pro-Pro)(10), using designed proteins in which this peptide is fused either NH(2)- or COOH-terminal to a nucleation domain, either T4-phage foldon or the disulfide knot of type III collagen [4].
• All polymorphs have the trans-trans-trans conformation of the N-N-C-C-N-N backbone, but the positions of the hydrogen atoms of the NH(2) groups relative to this backbone differ between the different polymorphs through variation of the torsion angle around each NH-NH(2) bond [5].

High impact information on azanylidene

• (2) Cavities in the interface between TBP and the minor-groove face of the AdMLP TATA box accommodate the exocyclic NH(2) groups of G in a TACA box and in a TATAAG box [6].
• We report that the human TP73 gene generates an NH(2) terminally truncated isoform [7].
• A peptide based on the NH(2) terminus of the C5aR and sulfated at these two tyrosines, but not its unsulfated analogue or a doubly sulfated control peptide, partially inhibited C5a association with its receptor [8].

• Its product, podocin, is a new member of the stomatin family, which consists of hairpin-like integral membrane proteins with intracellular NH(2)- and COOH-termini [10].

Chemical compound and disease context of azanylidene

• Using a model system of alkylsilane SAMs with different functional groups (X=OH, COOH, NH(2) and CH(3)) and an erythroleukemia cell line expressing a single integrin (alpha(5)beta(1)), the effect of surface properties on the cellular adhesion with adsorbed Fn layers was investigated [11].

Biological context of azanylidene

• Sequence-independent interactions involving the free peptidic NH(2) terminus are thought to be an essential feature of peptide binding to classical major histocompatibility complex (MHC) class I proteins [9].
• In vitro analysis revealed that NH(2)- and COOH-terminal truncations of Op18 have opposite effects on the rates of tubulin GTP hydrolysis [12].
• The overexpression of tagged cDNA constructs in keratinocytes revealed that the NH(2) terminus is essential for the nuclear localization, while the central domain is responsible for the interaction with EB1 and for the phenotype of transfected keratinocytes similar to terminal differentiation [13].
• A repeated sequence motif [EEX(4)](8) at the NH(2) terminus of RAP46 or BAG-1L, a larger isoform of RAP46, is responsible for this downregulation of GR activity [14].
• Although hVam6p exhibits homology to the Saccharomyces cerevisiae vacuolar protein sorting gene product Vam6p/Vps39p, the presence of a citron homology (CNH) domain at the NH(2) terminus is unique to the human protein [15].

Anatomical context of azanylidene

• Ugo1p appears to contain a single transmembrane segment, with its NH(2) terminus facing the cytosol and its COOH terminus in the intermembrane space [16].

• Overexpressing the entire N2-B region or its NH(2) terminus in cardiac myocytes greatly disrupted thin filament, but not thick filament structure [18].
• Like the NH(2) terminus of desmoplakin, that of periplakin localized to desmosomes; however, in addition, the periplakin NH(2) terminus accumulated at cell surface microvilli in association with cortical actin [19].

Associations of azanylidene with other chemical compounds

• Here, we characterize a new member of the family, beta-netrin. beta-Netrin is homologous to the NH(2) terminus of laminin chain short arms; it contains a laminin-like domain VI and 3.5 laminin EGF repeats and a netrin C domain [21].
• We find that the carbonyl oxygen on the backbone of the arginine finger supplied in trans by p120GAP (Arg-789) interacts with a water molecule in the active site that is forming a bridge between the NH(2) group of the Gln-61 and the gamma-phosphate of GTP [22].
• Different HhH cassettes fused with either NH(2) terminus or COOH terminus of DNA polymerases broaden the salt concentration range of the polymerase activity significantly (up to 0.5 M NaCl or 1.8 M potassium glutamate) [23].

• The Sec2p NH(2) terminus encodes an exchange factor for the Rab protein Sec4p [26].
