Formation of a heterooctameric complex between aspartate α-decarboxylase and its cognate activating factor, PanZ, is CoA-dependent

The existence of a fifth essential protein for pantothenate biosynthesis in some enteric bacteria has recently been reported by Stuecker et al. [10] and Nozaki et al. (in press) [9]. This protein, PanZ, catalyses the activation of the PanD zymogen to form ADC and is essential for prototrophic growth. In this paper, we characterise the interaction of PanZ with coenzyme A and a constitutively ina...

The Structure of the PanD/PanZ Protein Complex Reveals Negative Feedback Regulation of Pantothenate Biosynthesis by Coenzyme A

Coenzyme A (CoA) is an ubiquitous and essential cofactor, synthesized from the precursor pantothenate. Vitamin biosynthetic pathways are normally tightly regulated, including the pathway from pantothenate to CoA. However, no regulation of pantothenate biosynthesis has been identified. We have recently described an additional component in the pantothenate biosynthetic pathway, PanZ, which promot...

Arginyl-tRNA Synthetase Facilitates Complex Formation Between Seryl-tRNA Synthetase and its Cognate Transfer RNA

Several studies have revealed the involvement of multi aminoacyl-tRNA synthetase complexes (MSC) in archaeal and eukaryotic translation. Here we analyzed interactions of atypical Methanothermobacter thermautotrophicus seryl-tRNA synthetase (MtSerRS), transfer RNA (tRNA) and arginyl-tRNA synthetase (ArgRS). Surface plasmon resonance (SPR) was used to determine dissociation constants for the MtSe...

The Importance of α-CT and Salt bridges in the Formation of Insulin and its Receptor Complex by Computational Simulation

Insulin hormone is an important part of the endocrine system. It contains two polypeptide chains and plays a pivotal role in regulating carbohydrate metabolism. Insulin receptors (IR) located on cell surface interacts with insulin to control the intake of glucose. Although several studies have tried to clarify the interaction between insulin and its receptor, the mechanism of this interaction r...
