Example types with porphyrin
The same corpus examples are grouped by length and sentence type, making it easier to see the contexts in which the word appears:
This enzyme contains iron-porphyrin complexes, similar to that in hemoglobin. (11 words)
Chlorophyll contains a magnesium-porphyrin complexes, and vitamin B12 is a complex with cobalt and corrin. (16 words)
UVA plus porphyrin, on the other hand, led to ∼40% G→A (and C→T, with no preference for diPy), plus T→G and other transversions. (26 words)
Iron's shift to a higher oxidation state in Hb-O 2 decreases the atom's size, and allows it into the plane of the porphyrin ring, pulling on the coordinated histidine residue and initiating the allosteric changes seen in the globulins. (42 words)
Since many of these proteins contain globins and the heme moiety (iron in a flat porphyrin support), they are often called hemoglobins, even if their overall tertiary structure is very different from that of vertebrate hemoglobin. (36 words)
This results in the Fe 2+ ion switching to a low-spin configuration, resulting in a 20% decrease in ionic radius so that now it can fit into the porphyrin ring, which becomes planar. (34 words)

At the same time, the imidazole side-chain of the histidine residue interacting at the other pole of the iron is pulled toward the porphyrin ring.
Chlorophyll contains a magnesium-porphyrin complexes, and vitamin B12 is a complex with cobalt and corrin.
Heme is a good example: the iron atom is at the centre of a porphyrin macrocycle, being bound to four nitrogen atoms of the tetrapyrrole macrocycle.
Iron's shift to a higher oxidation state in Hb-O 2 decreases the atom's size, and allows it into the plane of the porphyrin ring, pulling on the coordinated histidine residue and initiating the allosteric changes seen in the globulins.
It is thus too large to fit inside the porphyrin ring, which bends instead into a dome with the Fe 2+ ion about 55 picometers above it.
Since many of these proteins contain globins and the heme moiety (iron in a flat porphyrin support), they are often called hemoglobins, even if their overall tertiary structure is very different from that of vertebrate hemoglobin.
This enzyme contains iron-porphyrin complexes, similar to that in hemoglobin.
This results in the Fe 2+ ion switching to a low-spin configuration, resulting in a 20% decrease in ionic radius so that now it can fit into the porphyrin ring, which becomes planar.
When the porphyrin ring is broken up, the fragments are normally secreted as a yellow pigment called bilirubin, which is secreted into the intestines as bile.
