This is the second set of Handbook of Porphyrin Science. Porphyrins, phthalocyanines and
their numerous analogues and derivatives are materials of tremendous importance in …

Haem is the major iron source for bacteria that develop in higher organisms. In these hosts,
bacteria have to cope with nutritional immunity imposed by the host, since haem and iron …

1. INTRODUCTION Heme proteins are among the most versatile players in the biological
milieu; their functions range widely and include electron transfer, catalysis, and small …

Iron is indispensable for the growth, development and well-being of almost all living
organisms. Biological systems from bacteria, fungi and plants to humans have evolved …

Reducing CO2 is a challenging chemical transformation that biology solves easily, with high
efficiency and specificity. In particular, formate dehydrogenases are of great interest since …

The characteristics of heme prosthetic groups and their binding sites have been analyzed in
detail in a data set of nonhomologous heme proteins. Variations in the shape, volume, and …

The secreted Mycobacterium tuberculosis (Mtb) heme binding protein Rv0203 has been
shown to play a role in Mtb heme uptake. In this work, we use spectroscopic (absorption …

Progesterone receptor membrane component 1 (PGRMC1) is a 25 kDa protein with an N-
terminal transmembrane domain and a putative C-terminal cytochrome b5 domain. Heme …

The extreme limitation of free iron has driven various pathogens to acquire iron from the host
in the form of heme. Specifically, several Gram-negative pathogens secrete a heme binding …

When challenged by low-iron conditions several Gram-negative pathogens secrete a
hemophore (HasA) to scavenge hemin from its host and deliver it to a receptor (HasR) on …
