Recombinant Human NMT1 Protein, N-His

Introduction

Recombinant Human NMT1 Protein, also known as N-myristoyltransferase 1, is a key enzyme involved in the post-translational modification of proteins. This protein is encoded by the NMT1 gene and plays a crucial role in a variety of cellular processes, making it a valuable tool in scientific research and potential therapeutic applications.

Structure of Recombinant Human NMT1 Protein

The Recombinant Human NMT1 Protein is a 52 kDa protein consisting of 471 amino acids. It is composed of two domains – an N-terminal catalytic domain and a C-terminal myristoyl-binding domain. The catalytic domain is responsible for the transfer of myristic acid to the N-terminal glycine of target proteins, while the myristoyl-binding domain helps in the recognition and binding of target proteins.

The crystal structure of Recombinant Human NMT1 Protein has been determined, revealing its unique three-dimensional structure. This structure provides insights into the mechanism of action of this enzyme and aids in the design and development of inhibitors and modulators.

Activity of Recombinant Human NMT1 Protein

The primary function of Recombinant Human NMT1 Protein is to catalyze the transfer of myristic acid from myristoyl-CoA to the N-terminal glycine residue of target proteins. This modification, known as N-myristoylation, is essential for the proper functioning and localization of many proteins involved in signal transduction, membrane targeting, and protein-protein interactions.

Recombinant Human NMT1 Protein has been found to have a broad substrate specificity, with the ability to myristoylate a wide range of proteins. This includes viral proteins, such as HIV-1 Gag and Rous sarcoma virus Gag, as well as cellular proteins, such as the α subunit of G proteins and Src family kinases.

In addition to its role in protein myristoylation, Recombinant Human NMT1 Protein has been shown to have other activities as well. It has been found to have protein kinase activity, phosphorylating certain substrates in vitro. It has also been reported to have RNA binding activity, suggesting a potential role in RNA metabolism.
