β-Galactosidase Deficiency in Colombia

Journal of Inborn Errors of Metabolism and Screening, 2015
β - Galactosidase (BGal) هو أول إنزيم يشارك في تقويض الدهون السفينغولية. ارتبط مرضان بشكل مباشر بنقصه: داء الغانغليوزيدات GM1 و Morquio B. Morquio B هو من بين أندر أنواع داء عديد السكاريد المخاطي (MPS). نهدف إلى توثيق نقص β - galactosidase في كولومبيا. قمنا بتقييم الكريات البيض من 1492 فردًا كولومبيًا أصحاء و 923 مريضًا، تمت إحالتهم بين عام 2005 وأغسطس

Heterologous expression of a recombinant lactobacillal -galactosidase in Lactobacillus plantarum: effect of different parameters on the sakacin P-based expression system [PDF]

, 2015
Background: Two overlapping genes lacL and lacM (lacLM) encoding for heterodimeric -galactosidase from Lactobacillus reuteri were previously cloned and over-expressed in the food-grade host strain Lactobacillus plantarum WCFS1, using the inducible ...

TNF receptor–related factor 3 inactivation promotes the development of intrahepatic cholangiocarcinoma through NF‐κB‐inducing kinase–mediated hepatocyte transdifferentiation

Hepatology, EarlyView., 2022
Abstract Background and Aims Intrahepatic cholangiocarcinoma (ICC) is a deadly but poorly understood disease, and its treatment options are very limited. The aim of this study was to identify the molecular drivers of ICC and search for therapeutic targets.

In vivo evidence for glycyl radical insertion into a catalytically inactive variant of pyruvate formate‐lyase

FEBS Letters, EarlyView.
Dimeric pyruvate formate‐lyase cleaves pyruvate using a radical‐based mechanism. G734 serves as a radical storage location, and the radical is transferred to the catalytic C419 residue. Mutation of the C418‐C419 pair causes loss of enzyme activity, but does not impede radical introduction onto G734. Therefore, cis‐ but not trans‐radical transfer occurs
