Heme
Types Major hemes There are several biologically important kinds of heme: The most common type is heme B; other important types include heme A and heme Thus cytochrome oxidase, which has two A hemes (heme a and heme a3) in its structure, contains two moles of heme A per mole protein. wikipedia.org

Heme A
Heme A is similar to heme o, in that both have this farnesyl addition at position 2 but heme O does not have the formyl group at position 8, still containing Like heme B, heme A is often attached to the apoprotein through a coordinate bond between the heme iron and a conserved amino acid side-chain. wikipedia.org

Question about flavodiiron protein I came across an article about flavodiiron proteins that are responsible for reducing ${\rm O}_2$ to ${\rm H}_2{\rm O}$ thereby protecting the anaerobic prokaryotes and some eukaryot...
No flavodiiron proteins are not haem proteins. See here for a simple depiction. Basically there is a flavin, and there are two iron atoms which go through a FeII/FeIII cycle during catalytic activity. These iron atoms are not held in haem, but rather via carboxylate ligands.

Heme O
Heme O (or haem O) differs from the closely related heme A by having a methyl group at ring position 8 instead of the formyl group. Heme O, found in the bacterium Escherichia coli, functions in a similar manner to heme A in mammalian oxygen reduction. wikipedia.org

Heme B
Heme B or haem B (also known as protoheme IX) is the most abundant heme. Hemoglobin and myoglobin are examples of oxygen transport proteins that contain heme B. The peroxidase family of enzymes also contain heme B. wikipedia.org

Heme transporter
A heme transporter is a protein that delivers heme to the various parts of a biological cell that require it. Heme transport Members of the SLC48 and SLC49 solute carrier family participate in heme transport across cellular membranes (heme-transporting ATPase). wikipedia.org
