Abstract: A modified DNase protein is described herein as well as pharmaceutical compositions comprising same, the modified DNase protein comprising a DNase polypeptide attached to at least two poly(alkylene glycol) moieties. Further described herein is a process of preparing a modified DNase protein, the process comprising: contacting the polypeptide with an agent that comprises a poly(alkylene glycol) attached to an aldehyde group, to obtain a conjugate of the polypeptide and the agent; and contacting the conjugate with a reducing agent.

Abstract: Modified DNase I protein in which one or more amino acids of a DNase I protein are modified non-cellularly, are provided. The modified DNase I protein exhibits a DNA hydrolytic activity in the presence of actin and an improved DNA hydrolytic activity compared to a homologous non-modified DNase I protein. Processes of preparing the modified DNase I protein and uses thereof in, for example, reducing a DNA content in sputum and/or in treating a disease or condition associated with excess extracellular DNA in a fluid, secretion or tissue of a subject, are also provided.
