Trim parentheses via tcl

I have the following URL and would like to remove the parentheses (both) by using an iRule (TCL):

http://ing1.example.com:31100/test1/test1.json/Streams(Type_4000000)

when HTTP_REQUEST {
  if { ([HTTP::host] eq "ing1.example.com") or ([HTTP::host] eq "ing1.example.com" ) and ([HTTP::uri] contains "Streams")}
      set NEW_URI [string trimleft [HTTP::uri] ( or )]
  }

Is it configured correctly?

thank you.

set old_uri [HTTP::uri]
HTTP::uri "[string map {( "" ) ""} $old_uri]"
}
}

use string map to remove ：
tcl test:
(bin) 68 % set uri "/test1/test1.json/Streams(Type_4000000)"
/test1/test1.json/Streams(Type_4000000)
(bin) 69 % set new_uri [string map {( "" ) ""} $uri]
/test1/test1.json/StreamsType_4000000
(bin) 70 %

  There was an error when trying to save, so I added braces {}
  {set new_uri [string map {( "" ) ""} $uri]}
  However, this iRule doesn't remove the parentheses. The URL contains also a port, is it needed at the HTTP::host ?
