His play King Baabu premiered in Lagos in 2001, a political satire on the theme of African dictatorship. In 2002, Methuen published a collection of his poems, Samarkand and Other Markets I Have Known. In April 2006, his memoir You Must Set Forth at Dawn was published by Random House. In 2006 he cancelled his keynote address for the annual ESA Writing Awards ceremony in Bangkok to protest the Thai military's successful coup against the government.Nonsteroidal topical treatments are treatments that contain ingredients other than steroids. Often, these prescription treatments contain active or synthetic vitamin D3, a derivative of vitamin A, or anthralin. There are a variety of reasons why your healthcare provider may recommend a nonsteroidal topical treatment, including the severity of your psoriasis and its location.

Activated by calcium, the enzyme digests proteins preferentially after hydrophobic amino acids (aliphatic, aromatic and other hydrophobic amino acids). Although calcium ions do not affect the enzyme activity, they do contribute to its stability. Proteins will be completely digested if the incubation time is long and the protease concentration high enough. By removing sms service provider singapore calcium ions, the stability of the enzyme is reduced, but the proteolytic activity remains. Proteinase K has two binding sites for Ca2+, which are located near the active site, but are not directly involved in the catalytic mechanism. The residual activity is sufficient to digest proteins, which usually contaminate nucleic acid preparations. Therefore, digestion with Proteinase K for nucleic acid purification is usually performed in the presence of EDTA (inhibition of metal ion-dependent enzymes such as nucleases).

Proteinase K is also stable over a wide pH range (4–12), with an optimum pH of 8.0. An elevation of the reaction temperature from 37 °C to 50–60 °C can increase the activity several-fold, as can the addition of 0.5–1% sodium dodecyl sulfate (SDS) or guanidinium chloride (3 M), guanidinium thiocyanate (1 M), and urea (4 M). The above-mentioned conditions increase the activity of proteinase K by making its substrate cleavage sites more accessible. Temperatures above 65 °C, trichloroacetic acid (TCA), or the serine protease inhibitors AEBSF, PMSF, or DFP inhibit the activity. Proteinase K will not be inhibited by guanidinium chloride, guanidinium thiocyanate,
