Influence of the amino acid moiety on deconjugation of bile acid amidates by cholylglycine hydrolase or human fecal cultures.

open access: yesJournal of Lipid Research, 1988
The influence of the chemical structure of the amino acid (or amino acid analogue) moiety of a number of synthetic cholyl amidates on deconjugation by cholylglycine hydrolase from Clostridium perfringens was studied in vitro at pH 5.4.

Digestion of Protein in Premature and Term Infants. [PDF]

open access: yes, 2012
Premature birth rates and premature infant morbidity remain discouragingly high. Improving nourishment for these infants is the key for accelerating their development and decreasing disease risk. Dietary protein is essential for growth and development of

The Modified Recombinant Proinsulin: A Simple and Efficient Way to Produce Insulin Glargine in E. coli

open access: yesResearch in Molecular Medicine, 2021
Background: Recombinant insulin glargine, a long-acting analog of insulin, is expressed as proinsulin in the host cell and, after purification and refolding steps, is processed to mature insulin by using trypsin and carboxypeptidase B. Because of several

Iron-binding fragments from the N-Terminal and C-Terminal regions of human lactoferrin [PDF]

open access: yes, 1978
Digestion of lactoferrin with pepsin at pH 3.0 gave an iron-binding half-molecule that represents the C-terminal part of the native protein. Tryptic or chymotryptic digestion of 30%/-iron-saturated lactoferrin yielded the N- and C-terminal half ...

Upregulation of Transglutaminase andε(γ-Glutamyl)-Lysine in the Fisher-Lewis Rat Model of Chronic Allograft Nephropathy [PDF]

open access: yes, 2014
Background. Tissue transglutaminase (TG2), a cross-linking enzyme, modulates deposition of extracellular matrix protein in renal fibrosis. This study aimed to examine TG2 and its cross-link product ε(γ-glutamyl)-lysine in the Fisher-Lewis rat renal ...

Multimodal Chromatography in the Downstream Processing of mAb‐Based Products: Mechanisms, Strategies, and Applications

open access: yesBiotechnology and Bioengineering, EarlyView.
ABSTRACT Multimodal chromatography has emerged as a powerful tool for the purification of monoclonal antibodies (mAbs) and their derivatives—including antibody fragments (Fabs), Fc‐fusions, bispecific (BsAb), and antibody–drug conjugates (ADCs)—offering enhanced selectivity through the integration of ionic, hydrophobic, hydrogen‐bonding, and π–π ...

Carboxypeptidase-catalyzed hydrolysis of C-terminal lysine: mechanism for in vivo production of multiple forms of creatine kinase in plasma.

open access: yesClinical Chemistry, 1984
Abstract Human myocardial creatine kinase isoenzyme MM is present as a single form in tissue, but upon its release into plasma two additional forms, with faster anodal migration, are apparent on polyacrylamide electrophoresis. We designate the three forms as MM3, MM2, and MM1 in increasing order of anodal mobility.

Isolation and amino acid sequence analysis of a 4,000-dalton dynorphin from porcine pituitary [PDF]

open access: yes, 1982
A 4,000-dalton dynorphin was isolated from porcine pituitary. It has 32 amino acids (Mr = 3,986), with the previously described heptadecapeptide (now called dynorphin A) at its amino terminus and a related tridecapeptide, dynorphin B, at its carboxyl ...

Purification, Fluorescent Labeling, and Detyrosination of Mammalian Cell Tubulin for Biochemical Assays

open access: yesCytoskeleton, EarlyView.
ABSTRACT Microtubules play essential roles in numerous cellular processes. All microtubules are built from the protein tubulin, yet individual microtubules can differ spatially and temporally due to their tubulin isotype composition and post‐translational modifications (PTMs).

Structural Basis for Catalysis by the Mono- and Dimetalated Forms of the \u3cem\u3edapE\u3c/em\u3e-Encoded \u3cem\u3eN\u3c/em\u3e-succinyl-L,L-Diaminopimelic Acid Desuccinylase [PDF]

open access: yes, 2010
Biosynthesis of lysine and meso-diaminopimelic acid in bacteria provides essential components for protein synthesis and construction of the bacterial peptidoglycan cell wall. The dapE operon enzymes synthesize both meso-diaminopimelic acid and lysine and,
