Tracheal cytotoxin (TCT) is a soluble piece of peptidoglycan (PGN) found in the cell wall of all gram-negative bacteria, but only some bacteria species release TCT including Bordetella pertussis, Vibrio fischeri, and Neisseria gonorrhoeae
Tracheal cytotoxin (TCT) is a 921 dalton glycopeptide released by Bordetella pertussis, Vibrio fischeri (as a symbiosis chemical), and Neisseria gonorrhoeae (among other peptidoglycan-derived cytotoxins it produces). Cundell, DR; Kanthakumar, K; Taylor, GW; Goldman, WE; Flak, T; Cole, PJ; Wilson, R (1994). "Effect of tracheal cytotoxin from Bordetella pertussis on human neutrophil function in
Fibroin is an insoluble protein present in silk produced by numerous insects
Fibroin is an insoluble protein present in silk produced by numerous insects, such as the larvae of Bombyx mori, and other moth genera such as Antheraea, Cricula, Samia and Gonometa. Silk in its raw state consists of two main proteins, sericin and fibroin, with a glue-like layer of sericin coating two singular filaments
Sericin is a protein created by Bombyx mori (silkworms) in the production of silk
A schematic illustration of silk fibers produced by silkworms: (A) the raw silk fiber is composed of two fibroin fibers held together with sericin covered with a protein coat. After degumming, the removal of sericin, the fibroin fibers are dissolved
Riboflavin and its breakdown products interact with DNA, making this system attractive in the photodisinfection of blood and blood products
The application of photosensitisers to tropical pathogens in the blood supply Mark Wainwright PhD, Mauricio S. Baptista, in Photodiagnosis and Photodynamic Therapy, 2011 Riboflavin As vitamin B2, riboflavin (Fig. 5) is an essential nutrient in humans. The Mirasol system (Navigant Biotechnologies Inc., CO, USA) utilises riboflavin as a photosensitiser in conjunction with long-wave ultraviolet
Peptidoglycan or murein is a unique large macromolecule, a polysaccharide, consisting of sugars and amino acids that forms a mesh-like peptidoglycan layer outside the plasma membrane
Not to be confused with glycopeptide, proteoglycan, or glycoprotein Peptidoglycan or murein is a unique large macromolecule, a polysaccharide, consisting of sugars and amino acids that forms a mesh-like peptidoglycan layer outside the plasma membrane, the rigid cell wall (murein sacculus) characteristic of most bacteria (domain Bacteria).

Acidophiles in acid mine drainage
Methods of pH homeostasis and energy generation in acidophiles (with reference to Baker-Austin & Dopson, 2007 and Apel, Dugan, & Tuttle, 1980): (1) Direction of transmembrane electrochemical gradient (pH) and blocking of H+ by the cell membrane; (2) Reversed membrane
Biomining or what I suspect “healthcare” (and much of the “food” industry) has been up to for a very, very long time
Biomining is the technique of extracting metals from ores and other solid materials typically using prokaryotes, fungi or plants (phytoextraction also known as phytomining or biomining). V. Sheoran, A. S. Sheoran & Poonam Poonia (October 2009). "Phytomining: A Review". Minerals Engineering. 22 (12): 1007–1019. doi:10.1016/j.mineng.2009.04.001. These organisms secrete different organic compounds
Cold-Food Powder or Five Minerals Powder, poisonous psychoactive drug popular during the Six Dynasties (220–589) and Tang dynasty (618–907)
Cold-Food Powder (Chinese: 寒食散; pinyin: hánshísǎn; Wade–Giles: han-shih-san) or Five Minerals Powder (Chinese: 五石散; pinyin: wǔshísǎn; Wade–Giles: wu-shih-san) was a poisonous psychoactive drug popular during the Six Dynasties (220–589) and Tang dynasty (618–907) periods of China. Terminology Both Chinese names hanshisan and wushisan have the suffix -san (散, lit. "fall apart; scattered"), which means "medicine in powdered form" in Traditional Chinese medicine. Wushi (lit. "five rock") refers to the component mineral drugs, typically: fluorite, quartz, red bole clay, stalactite,

Transferrins
Transferrins are not limited to only binding to iron but also to different metal ions.
Ceruloplasmin carries more than 95% of the total copper in healthy human plasma and in addition plays a role in iron metabolism. It was first described in 1948.
