Preparation and use of poly(hydroxyethyl methacrylate) cryogels containing L-histidine for β-casein adsorption.
J. Food Sci. 78(2) , E238-43, (2013) The objective of this study was to determine β-casein adsorption by using supermacroporous poly(2-hydroxyethyl methacrylate-N-methacryloyl-(l)-histidine methyl ester) [p(HEMA-MAH)] cryogel. β-Casein adsorption properties of p(HEMA-MAH) cryogel were studied fo... |

A proximal pair of positive charges provides the dominant ligand-binding contribution to complement-like domains from the LRP (low-density lipoprotein receptor-related protein).
Biochem. J. 443(1) , 65-73, (2012) The LRP (low-density lipoprotein receptor-related protein) can bind a wide range of structurally diverse ligands to regions composed of clusters of ~40 residue Ca2+-dependent, disulfide-rich, CRs (complement-like repeats). Whereas lysine residues from the lig... |

The biological activity of hydrogen peroxide. IV. Enhancement of its clastogenic actions by coadministration of L-histidine.
Mutat. Res. 198(1) , 233-40, (1988) An enhancing effect of L-histidine (L-His) was detected on the induction by hydrogen peroxide (H2O2) of chromosomal aberrations of both the chromosome type and the chromatid type, in human embryonic fibroblasts. The maximum efficiency of induction was about 8... |

Carbonic anhydrase activators: gold nanoparticles coated with derivatized histamine, histidine, and carnosine show enhanced activatory effects on several mammalian isoforms.
J. Med. Chem. 54(5) , 1170-7, (2011) Lipoic acid moieties were attached to amine or amino acids showing activating properties against the zinc enzyme carbonic anhydrase (CA, EC 4.2.1.1). The obtained lipoic acid conjugates of histamine, L-histidine methyl ester, and L-carnosine methyl ester were... |

Gas-phase structure of protonated histidine and histidine methyl ester: combined experimental mass spectrometry and theoretical ab initio study.
J. Phys. Chem. A 109(37) , 8329-35, (2005) Gas-phase H/D exchange experiments with CD3OD and D2O and quantum chemical ab initio G3(MP2) calculations were carried out on protonated histidine and protonated histidine methyl ester in order to elucidate their bonding and structure. The H/D exchange experi... |

Kinetic resolution of racemic alcohols using thioamide modified 1-methyl-histidine methyl ester.
J. Org. Chem. 73(21) , 8558-62, (2008) The low-molecular-weight and easily prepared N-thiobenzoyl 1-methyl-histidine methyl ester 3k was utilized to efficiently catalyze the kinetic resolution of racemic secondary alcohols. Comparison of the conformations of amide catalyst 3c and thioamide catalys... |

Structure and cooperativity of a T-state mutant of histidine decarboxylase from Lactobacillus 30a.
Proteins 46(3) , 321-9, (2002) Histidine decarboxylase (HDC) from Lactobacillus 30a converts histidine to histamine, a process that enables the bacteria to maintain the optimum pH range for cell growth. HDC is regulated by pH; it is active at low pH and inactive at neutral to alkaline pH. ... |

Enantioselective recognitions of chiral molecular tweezers containing imidazoliums for amino acids.
Chirality 21(5) , 539-46, (2009) Two kinds of novel chiral molecular tweezers containing imidazoliums were synthesized from L-alanine, L-phenylalanine, and L-glutamic acid. They are constructed by the chiral imidazolium pincers and two different spacers which are 1,3-bis (bromomethyl)benzene... |

Reaction of Lactobacillus histidine decarboxylase with L-histidine methyl ester.
Biochemistry 26(13) , 4082-5, (1987) L-Histidine methyl ester inactivates histidine decarboxylase in a time-dependent manner. The possibility was considered that an irreversible reaction between enzyme and inhibitor occurs [Recsei, P. A., & Snell, E. E. (1970) Biochemistry 9, 1492-1497]. We have... |

HME--a novel derivative for direct iodination in steroid radioimmunoassays.
J. Steroid Biochem. 28(6) , 663-7, (1987) Steroid derivatives containing histidine methyl ester (HME), instead of histamine, were prepared by mixed anhydride coupling. The derivatives were crystalline, and when labelled in microgram quantities by using Iodo-gen (exposure time 1 h) the yield of the im... |
