17393253-0	2007	Heterogeneity of proteinase inhibitors in the water-soluble organic matrix from the oyster nacre.	Water	46-51	endogenous retrovirus group K member 7	Homo sapiens	17-27	
17393253-1	2007	We extracted proteinase inhibitors from the nacre of the oyster Pinctada margaritifera with water.	Water	92-97	endogenous retrovirus group K member 7	Homo sapiens	13-23	
15623031-0	2004	[Inactivation of T4 phage in water environment using proteinase].	Water	29-34	endogenous retrovirus group K member 7	Homo sapiens	53-64	
15623031-3	2004	In the optimum conditions and 67.5 u/mL concentration, the inactivation rate of proteinase K to T4 phage in sterilized water and in sewage achieved 99.4% and 49.4% respectively in an hour, and achieved >99.9% and 81.1% in three hours.	Water	119-124	endogenous retrovirus group K member 7	Homo sapiens	80-90	
15623031-4	2004	The inactivation rate of the industrial proteinase 1398 to T4 phage in sterilized water achieved 74.4% in an hour.	Water	82-87	endogenous retrovirus group K member 7	Homo sapiens	40-50	
3203685-3	1988	Besides this Cys72, proteinase K has two disulfide bonds, Cys34--Cys123 and Cys178--Cys249, which contribute to the stability of the tertiary structure consisting of an extended central parallel beta-sheet decorated by six alpha-helices, three short antiparallel beta-sheets, 18 beta-turns and involving several internal, structurally important water molecules.

3203685-10	1988	Based on these experiments, a reaction mechanism is proposed where the peptide substrate forms a three-stranded antiparallel pleated sheet with the recognition site of proteinase K consisting of Ser132--Leu133--Gly134 on one side and Gly100--Ser101 on the other, followed by expulsion of the oxyanion hole water W335 and hydrolytic cleavage by the Asp39--His69--Serr224 triad.
