Journal ArticleDOI
Structural and Functional Analysis of a Conjugated Bile Salt Hydrolase from Bifidobacterium longum Reveals an Evolutionary Relationship with Penicillin V Acylase.
R. Suresh Kumar,James A. Brannigan,Asmita Prabhune,Archana Pundle,Guy Dodson,Eleanor J. Dodson,Cheravakkattu G. Suresh +6 more
TL;DR: The crystal structure of BSH reported here from Bifidobacterium longum reveals that it is a member of N-terminal nucleophil hydrolase structural superfamily possessing the characteristic αββα tetra-lamellar tertiary structure arrangement.
Journal ArticleDOI
Penicillin V acylase crystal structure reveals new Ntn-hydrolase family members
Cheravakkattu G. Suresh,Archana Pundle,H. SivaRaman,K.N. Rao,James A. Brannigan,Colin E. McVey,Chandra S. Verma,Zbigniew Dauter,Eleanor J. Dodson,Guy Dodson +9 more
TL;DR: The crystal structure of PVA was determined to establish the nature of its catalytic mechanism and to identify any biochemical and structural relationships with PGA and other Ntn (N-terminal nucleophile) hydrolases.
Journal ArticleDOI
Molecular features of bile salt hydrolases and relevance in human health.
Deepak Chand,Vellore Sunder Avinash,Yashpal Yadav,Archana Pundle,C.G. Suresh,Sureshkumar Ramasamy +5 more
TL;DR: This review reviews the available information on the characteristics of BSH enzymes to understand their interactions with a wide range of substrates and their myriad physiological roles, from bile resistance to signalling mechanisms.
Journal ArticleDOI
Extracellular bacterial synthesis of protein-functionalized ferromagnetic Co3O4 nanocrystals and imaging of self-organization of bacterial cells under stress after exposure to metal ions
Umesh Kumar,Ashvini Shete,Arti S. Harle,Oksana Kasyutich,Walther Schwarzacher,Archana Pundle,Pankaj Poddar +6 more
TL;DR: In this article, the authors reported the synthesis of single-crystalline, ferromagnetic Co3O4 nanoparticles functionalized with proteins using cobalt acetate as precursor at room temperature in aqueous medium by a metal-tolerant marine bacterium isolated from the coast of the Arabian Sea.
Journal ArticleDOI
Continuous ethanol production by yeast cells immobilized in open pore gelatin matrix
TL;DR: Saccharomyces uvarum cells immobilized in the porous carrier showed high ethanol productivities with a maximum value of 25 g/l when monitored in packed bed reactors at 35°C with continuous cane molasses feedstock containing 10% fermentable sugars.
