C20-0024. Most iron-containing proteins have a reddish color, and most copper proteins are blue. In contrast, zinc proteins are colorless. Why are zinc proteins colorless ... [Pg.1488]

Thus the question arises as to what forms of haem proteins and transition metals are available in vivo that are capable of mediating the formation of damaging initiating or propagating species, since the majority of the iron and haem proteins in the human body are protected in vivo from exerting pro-oxidant activities by their compart-mentalization within their functional locations in the haem and non-haem iron-containing proteins and enzymes. [Pg.46]

We thank Dr Mahesh Sundararajan for helpful discussion regarding the modelling of iron containing proteins and Dr Richard Bryce for discussion regarding the modelling of carbohydrates in solution. We also thank Dr James J. P. Stewart for helpful discussion regarding the gradient-based optimisation of semi-empirical parameters. [Pg.133]

Peroxidases are heme iron-containing proteins similar in structure to that of cytochromes P450. The major difference is that peroxidases have histidine as the axial ligand instead of cysteine, and there are also other polar amino acids close to the heme iron that help to catalyze the peroxidase function of the enzyme (41). The result is that the peroxidases very rapidly catalyze the reduction of hydroperoxides to alcohols (or water in the case of... [Pg.52]

There are many other proteins that contain iron in a form that is neither in haem nor in iron-sulfur clusters. We have already encountered the iron storage and transport proteins, ferritin and transferrin (see Chapter 8). We propose to discuss here two other classes of iron-containing proteins, those with mononuclear non-haem iron centres and those with dinuclear non-haem iron centres. [Pg.231]

The choice of iron chelators on the basis of both molecular and cellular criteria was discussed in 2003 (374). One 2005 review is concerned with the design of orally active iron chelators (375), another considers the prospects for effective clinical use of several hydro-x5rpyridinones, dealing with novel species such as the 1-allyl compound as well as with the established deferiprone (LI) and desferrioxamine (Desferal, DFO) (376). A review dated 2006 deals with relevance of iron mobilization from both transferrin and other iron-containing proteins by LI to the treatment of various anemias and other iron-overload conditions (377). Two 2007 reviews concentrate on LI, as the only hydroxypyridinone in general clinical use. One author concludes that, on balance, LI is to be preferred to DFO. This conclusion is on the grounds that, despite the not infrequent occurrence of minor side effects, the incidence of serious side effects... [Pg.220]

Iron is essential for life and is required for many different types of iron-containing proteins. Microbes and other organisms go to extraordinary lengths to acquire Fe. Many microbes secrete specific and high affinity Fe chelators known as siderophores. More than 200 are known in bacteria alone (Neilands 1981). Siderophores overcome the problem of the low solubility of Felll especially in oxidising environments, and... [Pg.76]
