Isolated mussel gill mitochondria

H2S consumption was exhibited by mitochondria isolated from the giUs of the marine ribbed mussel Geukensia dermssa, an inhabitant of sulfide-rich intertidal sediment, in an 

FIGURE 8.8 H2S production in vascular tissues. H2S production by aorta homogenate (upper panel), cultured rat vascular smooth muscle cells (VSMCs middle panel), and intact rat aorta occurs after the addition of substrate L-cysteine (L-cys) and cofactor pyridoxal L-phosphate (PLP) for the enzyme CGL located in vascular tissue. H2S production is inhibited after the CGL. 3 cyano-L-alanine (BCA) is added. Ferric Lucina pectinata hemoglobin 1 (metHb) is added to confirm H2S production. The quantity of metHb-sulfide produced, determined spectrophotometrically, matched the levels of H2S detected by the PHSS (after [41]).
