sqlite3.OperationalError... what is wrong in my sqlite syntax?

Python 3 + tkinter and sqlite3

I'm doing a mock application to save a piece of text in sqlite

here's the function:

 def saveNote(self,note_id):

    conn = db.connect(fname)
    c = conn.cursor()
    safeTitle=self.newNoteTitle.get()
    safeContents=self.newNoteText.get("1.0",tk.END)
    safeLink=self.newNoteLink.get()
    safeRemarks=self.newNoteRemarks.get()
    conn.execute('UPDATE notes SET (title,contents,remarks,link,created,last_modified,notebook_id) VALUES (?, ?, ?, ?, CURRENT_TIMESTAMP, CURRENT_TIMESTAMP, ?) WHERE notes_id=5', (safeTitle, safeContents, safeRemarks, safeLink, 1))
    conn.commit()
        self.master.destroy()

When executing the function, I get this error:

 conn.execute('UPDATE notes SET (title,contents,remarks,link,created,last_modified,notebook_id) VALUES (?, ?, ?, ?, CURRENT_TIMESTAMP, CURRENT_TIMESTAMP, ?) WHERE notes_id=5', (safeTitle, safeContents, safeRemarks, safeLink, 1))
sqlite3.OperationalError: near "(": syntax error

I don't quite understand why the syntax is wrong...(I'm new to python)...can anyone help me spot the mistake?

Thanks
