Description of Recombinant Human UBE2L3, N-His

Introduction

Recombinant Human UBE2L3, also known as Ubiquitin-conjugating enzyme E2 L3, is a recombinant protein that plays a crucial role in the ubiquitin-proteasome pathway. This pathway is responsible for the degradation of damaged or unwanted proteins in the cell, making UBE2L3 an important player in cellular homeostasis and regulation.

Structure of Recombinant Human UBE2L3

UBE2L3 is a member of the E2 family of ubiquitin-conjugating enzymes, which are responsible for transferring ubiquitin molecules to target proteins. It is composed of 148 amino acids and has a molecular weight of approximately 17 kDa. The protein has a conserved catalytic core domain, which is essential for its enzymatic activity. UBE2L3 also contains a C-terminal extension that is involved in protein-protein interactions, allowing it to interact with other proteins in the ubiquitin-proteasome pathway.

Enzymatic Activity of Recombinant Human UBE2L3

The main function of UBE2L3 is to catalyze the transfer of ubiquitin from an E1 ubiquitin-activating enzyme to a target protein. This process, known as ubiquitination, marks the target protein for degradation by the proteasome. UBE2L3 specifically interacts with an E3 ubiquitin ligase, which helps to recognize and bind to the target protein, allowing for efficient ubiquitination. UBE2L3 has been shown to have a high affinity for its target proteins, making it a key player in the ubiquitin-proteasome pathway.
