Abstract
The reactivity of inorganic sulfide species toward heme peptides was explored under biorelevant conditions in order to unravel the molecular details of the reactivity of the endogenous hydrogen sulfide toward heme proteins. Unlike ferric porphyrinates, which are reduced by inorganic sulfide, some heme proteins can form stable Fe(III)-sulfide adducts. To isolate the protein factors ruling the redox chemistry, we used as a system model, the undecapeptide microperoxidase (MP11), a heme peptide derived from cytochrome c proteolysis that retains the proximal histidine bound to the Fe(III) atom. Upon addition of gaseous hydrogen sulfide (H2S) at pH 6.8, the UV-vis spectra of MP11 closely resembled those of the low-spin ferric hydroxo complex (only attained at an alkaline pH) and cysteine or alkylthiol derivatives, suggesting that the Fe(III) reduction was prevented. The low-frequency region of the resonance Raman spectrum revealed the presence of an Fe(III)-S band at 366 cm(-1) and the general features of a low-spin hexacoordinated heme. Anhydrous sodium sulfide (Na2S) was the source of sulfide of choice for the kinetic evaluation of the process. Theoretical calculations showed no distal stabilization mechanisms for bound sulfide species in MP11, highlighting a key role of the proximal histidine for the stabilization of the Fe(III)-S adducts of heme compounds devoid of distal counterparts, which is significant with regard to the biochemical reactivity of endogenous hydrogen sulfide.

Abstract
In the absence of heme cofactor, the water-soluble domain of rat microsomal cytochrome b5 (cyt b5) contains a long flexible region within its 42-residue heme-binding loop. Heme capture induces this region to fold into a well-defined structure containing helices H3-H5, each separated by a turn, with His39 and His63 serving as axial ligands to the heme iron. We have shown that the H4 region of the apoprotein has the greatest tendency for disorder within the isolated binding loop. Here, the effect of the His63-iron bond and proximity of heme plane on the population of helical conformation in H4 and H5 was investigated by synthesis and characterization of a peptide-sandwiched mesoheme construct in which two H4-H5 peptides were covalently attached to a single cofactor. Spectroscopic data indicated that a holoprotein-like bis-histidine coordination state was achieved over a pH range from 7 to 9. Trifluoroethanol titrations of the construct and the analogous free peptide under these pH conditions revealed that heme proximity and iron ligation were insufficient to promote helix formation in H4 and H5. These observations were used to assess the role of disordered regions in heme capture and the loop-scaffold interface in holoprotein folding and stability.

Abstract
The equilibrium complexity involving different axially coordinated hemes is peculiar to hemoglobins. The pH dependence of the spontaneous exchange of ligands in the extracellular hemoglobin from Glossoscolex paulistus was studied using UV-Vis, EPR, and CD spectroscopies. This protein has a complex oligomeric assembly with molecular weight of 3.1 MDa that presents an important cooperative effect. A complex coexistence of different species was observed in almost all pH values, except pH 7.0, where just aquomet species is present. Four new species were formed and coexist with the aquomethemoglobin upon acidification: (i) a "pure" low-spin hemichrome (Type II), also called hemichrome B, with an usual spin state (d(xy))(2)(d(xz),d(yz))(3); (ii) a strong g(max) hemichrome (Type I), also showing an usual spin state (d(xy))(2)(d(xz),d(yz))(3); (iii) a hemichrome with unusual spin state (d(xz),d(yz))(4)(d(xy))(1) (Type III); (iv) and a high-spin pentacoordinate species. CD measurements suggest that the mechanism of species formation could be related with an initial process of acid denaturation. However, it is worth mentioning that based on EPR the aquomet species remains even at acidic pH, indicating that the transitions are not complete. The "pure" low-spin hemichrome presents a parallel orientation of the imidazole ring planes but the strong g(max) hemichrome is a HALS (highly anisotropic low-spin) species indicating a reciprocally perpendicular orientation of the imidazole ring planes. The hemichromes and pentacoordinate formation mechanisms are discussed in detail.

Abstract
Microperoxidases were initially isolated as peptide fragments containing covalently bound heme and are derived from naturally occurring c-type cytochromes. They are not only used as model compounds but also have potential applications as biosensors, electron carriers, photoreceptors, microzymes, and drugs. In a systematic attempt to define the minimal requirements for covalent attachment of hemes to c-type cytochromes, we have succeeded to produce artificial microperoxidases with peptide sequences that do not occur naturally and can be manipulated. The in vivo production of these microperoxidases requires targeting of the peptide to the bacterial periplasm, proteolytic processing of the signal peptide, and covalent attachment of heme to the signature motif CXXCH by the cytochrome c maturation proteins CcmA-H. The peptides that bind heme carry a C-terminal histidine tag, presumably to stabilize the heme peptide. We present a heme cassette that is the basis for the de novo design of functional hemoproteins.

Abstract
To investigate the nitrite reducing activity of microperoxidases (mps) in the presence of methyl viologen and dithionite, the fragments C14-K22 (mp9), V11-L32 (mp22), and G1-M65 (mp65) containing heme were prepared by enzymatic hydrolysis of commercially equine heart cytochrome c (Cyt c), in which His is axially coordinated to heme iron, and acts as its fifth ligand. The nitrite reducing activity of mps was measured under anaerobic condition, and the nitrite reducing activity of mps increased with the cutting of the peptide chain. The activity of the shortest nonapeptide mp9 was approximately 120-fold that of Cyt c (104 amino acid residues) and 3.2-fold that of nitrite reductase (EC 1.7.7.1) from Escherichia coli. In the nitrite reduction by mp, nitrite was completely reduced to ammonia. We presumed that ferrous mps reduced NO2- to NO by donating one electron, the NO was completely reduced to NH4+ under anaerobic condition via ferrous-NO complexes as a reaction intermediate using visible spectra and ESR spectra, and this overall reaction was a 6-electron and 8-proton reduction. Sepharose-immobilized mp9 had a nitrite reducing activity similar to that of mp9 in solution, and the resin retained the activity after five uses and even 1-year storage. The mp will be able to use as a substitute for nitrite reductase.
