Histidine decarboxylase of Lactobacillus 30a. Comparative sequences of the beta chain from wild type and mutant enzymes.
Manual and automated sequencing of peptides isolated from tryptic, chymotryptic, and Staphylococcus aureus V8 protease digests of the beta chain of histidine decarboxylase from Lactobacillus 30a have established the following sequence for the wild type protein: NH2-Ser-Gly-Leu-Asp-Ala-Lys-Leu-Asn-Lys-Leu-Gly-Val-Asp-Arg-Ile-Ala-Ile-Ser-Pro -Tyr-Lys-Gln-Trp-Thr-Arg-Gly-Tyr-Met-Glu-Pro-Gly-Asn-Il...
متن کاملStructure and cooperativity of a T-state mutant of histidine decarboxylase from Lactobacillus 30a.
Histidine decarboxylase (HDC) from Lactobacillus 30a converts histidine to histamine, a process that enables the bacteria to maintain the optimum pH range for cell growth. HDC is regulated by pH; it is active at low pH and inactive at neutral to alkaline pH. The X-ray structure of HDC at pH 8 revealed that a helix was disordered, resulting in the disruption of the substrate-binding site. The HD...

Bacteriol. 87:370-376. 1964.-The nutritional requirements of Lactobacillus 30a include each of the naturally occurring amino acids, several B vitamins, ascorbic acid, glucose, acetate, and oleate. The nutritional requi...
متن کاملpH-induced structural changes regulate histidine decarboxylase activity in Lactobacillus 30a.
Histidine decarboxylase (HDC) from Lactobacillus 30a produces histamine that is essential to counter waste acids, and to optimize cell growth. The HDC trimer is active at low pH and inactive at neutral to alkaline pH. We have solved the X-ray structure of HDC at pH 8 and revealed the novel mechanism of pH regulation. At high pH helix B is unwound, destroying the substrate binding pocket. At aci...

از محوری ترین اثراتی که یک فیلم سینمایی ایجاد می کند دیالوگ هایی است که هنرپیش گان فیلم میگویند. به زعم یک فیلم ساز, یک شیوه متأثر نمودن مخاطب از اثر منظوره نیروی گفتارهای گوینده, مثل نیروی عاطفی, ترس آور, غم انگیز, هیجان انگیز و غیره, است. این مطالعه به بررسی این مسأله مبادرت کرده است که آیا نیروی فراگفتاری هنرپیش گان به مثابه ی اعمال گفتاری در پنج فیلم هالیوودی در نسخه های دوبله شده باز تولید...
