Rapid identification of Branhamella catarrhalis with 4-methylumbelliferyl butyrate.
J. Clin. Microbiol. 26 , 1227, (1988) Branhamella catarrhalis can be distinguished from Neisseria spp. by the presence of butyrate esterase. This enzyme can be rapidly detected when 4-methylumbelliferyl butyrate is used as the substrate. All B. catarrhalis strains tested gave a positive fluoresce... |

Characterization of an acidic cold-adapted cutinase from Thielavia terrestris and its application in flavor ester synthesis.
Food Chem. 188 , 439-45, (2015) An acidic cutinase (TtcutB) from Thielavia terrestris CAU709 was purified to apparent homogeneity with 983 Um g(-1) specific activity. The molecular mass of the enzyme was estimated to be 27.3 and 27.9 kDa by SDS-PAGE and gel filtration, respectively. A pepti... |

Fluorescence spectroscopic analysis of the structure and dynamics of Bacillus subtilis lipase A governing its activity profile under alkaline conditions.
Eur. Biophys. J. 44 , 655-65, (2015) Because of their vast diversity of substrate specificity and reaction conditions, lipases are versatile materials for biocatalysis. Lipase A from Bacillus subtilis (BSLA) is the smallest lipase yet discovered. It has the typical α/β hydrolase fold but lacks a... |

Purification and properties of digestive lipases from Chinook salmon (Oncorhynchus tshawytscha) and New Zealand hoki (Macruronus novaezelandiae).
Fish Physiol. Biochem. 36(4) , 1041-60, (2010) Lipases were purified from delipidated pyloric ceca powder of two New Zealand-sourced fish, Chinook salmon (Oncorhynchus tshawytscha) and hoki (Macruronus novaezelandiae), by fractional precipitation with polyethylene glycol 1000, followed by affinity chromat... |

Design, synthesis, and X-ray analysis of a glycoconjugate bound to Mycobacterium tuberculosis antigen 85C.
Bioconjug. Chem. 23(12) , 2403-16, (2012) Tuberculosis (TB) is a global health threat with nearly 500 000 new cases of multidrug-resistant TB estimated to occur every year, so new drugs are desperately needed. A number of current antimycobacterial drugs work by interfering with the biosynthesis of ke... |

Comparison of three rapid methods, tributyrine, 4-methylumbelliferyl butyrate, and indoxyl acetate, for rapid identification of Moraxella catarrhalis.
J. Clin. Microbiol. 32(5) , 1362-3, (1994) Moraxella catarrhalis can easily be differentiated from other oxidase-positive, gram-negative cocci with tributyrine, 4-methylumbelliferyl butyrate, or indoxyl acetate. All M. catarrhalis give positive reactions, and all Neisseria spp. give negative reactions... |
